Creating your own sourdough starter: the path to great bread



Whether it conjures up a crusty, flavorful loaf of bread or a bubbling crock of flour/water starter, sourdough is a treasured part of many bakers’ kitchens.

But where does the path to sourdough bread begin? And how do you start?

Start in your own home kitchen. And begin by creating your own sourdough starter.

First, a word of advice. Sourdough baking is as much art as science. This method for making sourdough starter isn’t an exact match for the one you read on another site, or in a cookbook, or in your great-grandma’s diary.

If you have a process you’ve successfully followed before, then hey, stick with it. Or try this one and compare. All good.

OK, ready? Let’s go.

Did you know that by clicking anywhere on this block of pictures, you can enlarge them to full size? Go ahead, give it a try; it’ll work for any of our gridded photos.

The following timeline assumes you can find a relatively warm place (68°F to 70°F) to grow your starter. More on that below.

Day 1: Combine 4 ounces (1 cup) whole rye flour (pumpernickel) or whole wheat flour with 4 ounces (1/2 cup) non-chlorinated cool water in a non-reactive container. Glass, crockery, stainless steel, or food-grade plastic all work fine for this. Here, I’m using a 4-cup glass measure.

Note that whole grain flour (whole wheat or rye) is used at the beginning of the process. This is because whole grains contain more nutrients and sourdough-friendly microorganisms than all-purpose flour.

It’s also important to feed your starter with non-chlorinated cool water; from now on, we’ll refer to this simply as “water.”

Stir everything together thoroughly; make sure there’s no dry flour anywhere. Cover the container loosely and let the mixture sit at warm room temperature (about 70°F) for 24 hours.

A note about room temperature: the colder the environment, the more slowly your starter will grow. If the normal temperature in your home is below 68°F, we suggest finding a smaller, warmer spot to develop your starter.

For instance, try setting the starter atop your water heater, refrigerator, or another appliance that might generate ambient heat. Or, set it near a heat source (baseboard heater, etc.).

Another option: set the container of starter on a folded dish towel laid atop a heating pad on its lowest setting – as I’ve done in the photo above.

A temperature-controlled bread proofer is the absolute ideal solution; if you bake lots of yeast bread, you might consider investing in one of these tools.

Day 2: You may see no activity at all in the first 24 hours, or you may see a bit of growth or bubbling.

Either way, discard half the starter (4 ounces), and add to the remainder 4 ounces (a scant 1 cup) King Arthur Unbleached All-Purpose Flour, and 4 ounces (1/2 cup) cool water (if your house is warm); or lukewarm water (if it’s cold).

Mix well, cover, and let the mixture rest at room temperature for 24 hours.

Note: Why do you need to discard half the starter? It seems so wasteful…

Well, it’s necessary for three reasons. First, unless you discard, eventually you’ll end up with The Sourdough That Ate Milwaukee – too much starter. Second, keeping the starter volume the same helps balance the pH. And third, keeping the volume down offers the yeast more food to eat each time you feed it; it’s not fighting with quite so many other little yeast cells to get enough to eat.

Also, you don’t have to discard it if you don’t want to; you can give it to a friend, or use it to bake. There are quite a few recipes on our site using “discard” starter, including sourdough pizza crust, sourdough pretzels, and my all-time favorite waffles.

Days 3, 4, & 5: By the third day (pictured top left), you’ll likely see some activity – bubbling; a fresh, fruity aroma, and some evidence of expansion. It’s now time to begin two feedings daily, as evenly spaced as your schedule allows.

For each feeding, weigh out 4 ounces starter; this will be a generous ½ cup, once it’s thoroughly stirred down. Discard any remaining starter.

Add 4 ounces (a scant 1 cup) King Arthur Unbleached All-Purpose Flour, and 4 ounces (1/2 cup) water to the 4 ounces starter.

Mix the starter, flour, and water, cover, and let the mixture rest at room temperature for approximately 12 hours before repeating.

Repeat two-a-day feedings on days 4, 5, and as many days as it takes for your starter to become very active.

The photo at bottom left shows the starter 12 hours after it’s been fed on day 3. Pictured at bottom right is that same starter, 12 hours after feeding, on day 6 – see how vigorous it’s become?

After about a week of consistent feeding, your starter should be ready to use in a sourdough bread recipe.


How do you know when your starter is ready to use?

After 12 hours, the starter will have risen nicely. You’ll see lots of bubbles; there may be some little “rivulets” on the surface, full of finer bubbles.

Also, the starter should have a tangy aroma – pleasingly acidic, but not overpowering.

The starter should at least double in volume 12 hours after it’s been fed; in the pictures above, it’s taken about 4 hours to double; so this starter is ready.

Here’s our starter, 1 week after we began the process: I’d say that’s good to go.

Once the starter is ready, give it one last feeding. Pour off all but 4 ounces. Feed as usual. Let the starter rest at room temperature for 6 to 8 hours; it should be active, with bubbles breaking the surface.

Remove however much starter you need for your recipe (no more than 8 ounces, about 1 cup); and transfer the remaining 4 ounces of starter to its permanent home: a crock, jar, or whatever you’d like to store it in long-term.

Ah, success…

But wait – what if things haven’t gone exactly according to schedule?

No worries. If, after a week, your starter isn’t ready, don’t lose heart; keep feeding it regularly, and it will gain strength – really!

Be patient. The conditions in your kitchen may be more or less conducive to building a starter, depending on room temperature, the season, humidity, or how much you’ve been baking.

Remember, the keys to developing a successful starter are using good (unbleached) flour; having a consistent feeding schedule, and ripening (growing) the starter in an environment that’s adequately warm (at least 68°F, and preferably in the 70s).

When your starter is strong enough, it’s time to go ahead and make your favorite sourdough bread.

Once your starter has been fed, and you’re ready to mix up your bread dough, you’ll want to reserve and maintain a small portion of the ripe (fed) starter (about 4 ounces; about 1/2 cup, stirred down)  for future baking. Unless you plan on continuing to feed the starter twice a day, refrigerate it for future use.

Good luck! And enjoy.

Next: maintaining your starter.

    How does one find that water? Any help on that would be appreciated. Thanks!

    Any bottled water is fine – any grocery, convenience store, or supermarket would carry it. Good luck! PJH

    1. The Baker's Hotline

      Sourdough starters traditionally do not use added commercial yeast. In this case the flour and water attracts the natural yeast in the air! This yeast is what is used to ferment your starter and leaven your dough. Jon@KAF

    2. katiu

      Or… If you keep a Britta (or other) pitcher of filtered water in your fridge/kitchen, that works just fine. Measure it out, nuke just until lukewarm, and you’re ready to go!

    3. Pat Babcock

      Boil a pot of water for 5-10 minutes, cover, turn off heat, allow to cool, the carefully pour off of any white, chalky sediment than may be present. This removes not only the chlorine, but also reduces the minerals in the water..

    4. Scott Breidenbach

      Very new to this, but am excited to try. I have mixed my flour and water for Day one, and I followed the measurements exactly. It is very thick and gummy like! Just want to be sure this sounds right. I did my best to mix thoroughly, but at this point it is very hard to manipulate.


    5. PJ Hamel , post author

      Scott, sounds like you may have been a bit heavy-handed with the flour; the mixture should be thicker than pancake batter, but not something you could easily pick up and work with; it should be “goopy” (how’s that for a technical term?). Add a bit more water next time, and you should be fine. Good luck – PJH

    6. Diane

      Using water from a Britta Filter or another that removes chlorine and other chemicals should do the trick too.

    7. Carol Ann Speight

      1. I love your site!
      2. Can’t seem to find a “print option” for this soudough recipe????
      3. Also would like to know IF you have a Chelsa bun (sourdough recipe)?
      4. Thanks & keep great work!
      5. Ciao! ;)

    8. The Baker's Hotline

      I’m sorry Carol, these instructions are only found via our blog, so there is no printer friendly version. I will also pass along the suggestion about the sourdough Chelsea Bun recipe as we do not have one! Happy baking. Jon@KAF

    9. The Baker's Hotline

      You may choose to use either cups or ounces – 1 cup or 4 oz of flour combined with 1/2 c. or 4 oz of water. Hope that helps horto! Elisabeth@KAF

    10. marty

      Carol ann, try E-Mailing the recipe to a friend then printing it oput. See if that would work

    11. Katt

      Is it just me? Am I crazy? Did I misread?
      The instructions say “Combine 4 ounces (1 cup) whole rye flour (pumpernickel) or whole wheat flour with 4 ounces (1/2 cup) non-chlorinated cool water…”
      Which is it? 4oz, or 1 cup? Are we looking for equal parts water and flour, or 1/2c water to 1c flour?
      A full cup is 8oz – and a half-cup is 4oz. Yet, the instructions say to combine 4oz Whole Rye OR Whole Wheat…. So are we shooting for 1/2 cup of rye and 1/2 cup of water? or 1/2 of each, and then add 1 cup of water?
      Thanks for the clarification! – Katt

    12. The Baker's Hotline

      Hello Katt! This is actually a common confusion among many bakers. While 1 cup does equate to 8 fluid ounces, other ingredients (such as flour) do not. Flour can range quite a bit when measuring by volume, depending on the type and measuring method. A King Arthur cup of whole wheat or rye weighs about 4 ounces, this is why we feed with 1 cup of flour to 1/2 cup of water or 4 ounces each by weight. The method you choose is up to you, but we always prefer weighing. Jon@KAF

    13. Dee Stonewall

      I use — and always have used (for years) — bottled distilled water bought at any grocery store. Why? Because distilled water has chemicals, minerals, and most importantly, chlorine, removed from the water. A gallon of distilled water is approximately $0.75 to $1.00 at your local grocery store.

    14. Norman Andresen

      To obtain dechlorinated water draw a volume (quart) from your tap. Allow to sit out overnight in an open bowl. I use a large measuring cup. In the morning almost all of the chlorine will have distilled off. This is the direction received during a sourdough baking class at Zingerman’s Bakehouse in Ann Arbor. I have been doing this regularly when I am to bake. I store the dechlorinated water in a cleaned milk jug. I use this water for all my baking no matter what is to be baked.

  2. bgwilson

    Why do you discard all but 4 oz of starter every time you feed the starter? Is that you prevent you form having a huge bowl of starter, or is there a “bread science” reason?

    Yes, to prevent you from ending up with too much starter; but most of all, to concentrate the yeast/lactobacilli in a smaller amount of space, so it can grow more quickly – not as much competition for the available food. PJH

    1. Pat Babcock

      You discard half only to reduce volume. Unlike fermenting liquids, the microorganisms in a sourdough starter – particularly a 100% hydration sponge as this method produces – are fairly evenly distributed throughout (statistically speaking). The only way in which the concentration would be increased by discarding half would be if this were not true, and they flocculated to the bottom as some yeasts do in liquids. If you keep the 1:1 mass (always weigh your ingredients to improve the consistency of your results!) ratio of starter to 100% hydration dough in your feedings, the yeast and microorganisms will thrive. In terms of pH as well – if the ratio is kept, the impact to pH is the same, whether discarding half or not. If you must discard, give it away, or turn it into the soil of your acid-loving outdoor plants and flowers. Me? I typically bake it away :)

      Note that sourdough starters store long term very well – I typically only have time to bake at home in the winter months, yet my sourdough starter is about 30 years old (closer to 35, now). Feed it, cover lightly. When it starts to rise, cover with plastic wrap secured by a rubber band or other suitable “burpable” means, and put it in the back of the refrigerator. Make sure your cover is secure – there are odors and microorganisms in refrigerators that will flavor and/or ruin your starter. When ready to use again, check the surface of your starter and scrape off any surface molds (have never experienced any, but molds are hearty beasts, so there is that potential) – don’t worry about any liquid that may have come to the surface. Leave it covered on your countertop until it warms to room temperature, then stir it thoroughly to aerate it; then feed it, stirring the dough into the starter thoroughly. It should perk right back up. If, after time, your starter starts to lose its acidity, your yeast culture has finally outcompeted your lactobacillus. No worries! Start a new starter as instructed here, then, after it has soured nicely, start adding back some of your old starter to help regain the flavor profile and strength of the former starter. Don’t add it all back, though, or you’ll shortly be back to an insipid starter – all yeast and no lacto!

      Finally, you can add starter to any recipe, as long as you maintain the 100% hydration (1:1 ratio of flour to water by weight) in your starter. Simply substitute a quantity of starter for a portion of the water and flour in the recipe. You deduct 1/2 as much each of the water and flour in the recipe as the weight of starter you added – for instance, if you add 2 ounces of starter to a recipe, deduct 1 ounce from the amount of each the water and the flour the recipe calls for. If your starter is very strong, eliminate the yeast – but if your recipes calls for “quick rise” yeast, or if your time is very limited, you will still need some added yeast – try half, and work from there as you adjust your recipe to use the starter.


  3. Stephie

    I tried to find an answer before asking but my searches just gave me more recipes. I’m wondering why you have to discard so much of the starter as you feed it and it grows? Why not use what would be thrown out for a second starter? Or would that be too much?

    All this effort and time for something so delicious, I guess this is why a good (though small) loaf of sourdough bread at the local grocery store costs over $5 (!!).

    The discard is to keep the ph of the starter in balance. you may use the discard to begin a second starter, or gift a baking friend, or use it for sourdough pancakes: Recipe here.

    This is wonderful information. I have always been interested in sourdough breads, and last week I got some of the KAF starter. I’ve just been following the instructions step by step that came with the starter, and so far, everything seems to be working. This is information in this blog, however, answers a lot of my questions about it. The reason I’m writing is to say that, wow, the rustic bread that I made is amazing (and all gone, I might add!). It’s the best bread I’ve ever made. And so easy to make. We’re planning to live on it now. Who needs anything else! The flavor and texture are way beyond my expectations. I’m trying to make a lot of it this week because I have a lot of company for the holiday. So far, so good. Thank you, KAF.

  5. "Hopeful Baker Sara"

    This is so happening this weekend!

    You go, girl!! I know your good karma will produce a fabulous, strong starter and wonderful bread. Stay tuned for our next blogs: maintaining your starter, and a wonderful recipe for sourdough bread with no added yeast… Happy Easter – PJH

  6. argentyne

    I only argue that sometimes, you can get a starter that is just completely retarded in its growth.

    I had one that you could feed as many times as you wanted and keep in a nice warm spot, but it would take weeks to double in volume even once.

    I finally gave up on that one.

    I do have one that was made almost exactly like these instructions that it really is trying to be the starter who ate the world. I gave a small spoonful to a friend and it tried to eat her fridge the next day. But it makes wonderful sourdough pancakes. :D

    Sourdough is so quirky – well, its just like us, a living, unpredictable entity! And some sourdoughs, as you say, have real personalities – I guess that’s why we name them. Enjoy – PJH

  7. Alun

    You guys must be psychic, I’ve been trying to make a starter for the past week with your flour…

    Alun, hopefully the photos will help. It can be tricky; I was having trouble until I broke out the heating pad. 60°F is just too cool to get anything going very quickly. Good luck! PJH

  8. MGW960W

    If you’ve fed your starter with equal parts flour and water by weight, it’s easy to substitute the part of the starter that would be thrown out before feeding for part of the ingredients in any recipe that calls for yeast. Just use the weight recipe amounts rather than the volume amounts. If you are “throwing out” (stirring into a recipe) four ounces of unfed starter, subtract two ounces of liquid and two ounces of flour from the recipe amounts to be added. You may need to cut back on the yeast a little, too. I do this with yeast recipes routinely, since I couldn’t possibly discard my much-loved starter. Also, we filter our water with a Brita carafe and that eliminates the chlorine.

    Great tip – I often use the “discard” in bread, just as you say. Also use it in any recipe calling for flour/liquid, where the liquid can be water; I sometimes use it in cake, pancakes, muffins… PJH

  9. infernalringing

    How do you know the ph levels in your starter? Is it about smell, taste, or growth rate, or what? Also, I have a thing against all-purpose flour. I grind my own wheat and usually have 3-5 types of berries on hand. What are your thoughts on using freshly ground white-wheat or hard red winter wheat or even soft red spring wheat instead of AP white? I know rye behaves differently, so right now I am building a rye starter using only whole rye flour, but I wonder about adding some rye to my basic starter. Your instructions for the starter for sale on your website says to add twice as much flour as water each time you feed it. Why is the ratio different than this “create-your-own” version? And finally, no matter how I cover my starters, my regular one (bought on your website) always develops a “crust” on top. My rye one never does. I usually just stir this back in when I am feeding it and it dissolves just fine. Is the crust thing normal? Thanks!

    I don’t test the pH levels in my starter (though it IS possible to get test strips from scientific supply companies)… Let me answer your questions in order here-
    1) Making starter from freshly ground wheat. You can do this, but run a fairly significant risk of it eventually going bad. Jeff Hamelman, one of our SD gurus, says he’ll use some whole grain to start a starter, but then switches over to feeding it with AP. If you do want to feed it with whole grains, it’s fine – but don’t leave it out on the counter, it’ll have to live, long-term, in the fridge.
    2) The instructions for adding twice as much flour as water refer to volume – you feed with 1 cup flour and 1/2 cup water. By weight, they’re the same – about 4 ounces.
    3) Not sure about the crust – mine never develops a crust, but instead ends up with liquid on top. Are you keeping it at room temperature, or in the fridge? Maybe it’s not covered well enough? Maybe you live in a particularly dry climate? But whatever, just stirring it back in, as you do, is fine. Good luck- PJH

  10. juthurst

    Great info as usual:)
    I have also read, in Leader and Blahnik’s “Bread Alone”,
    that the more natural (less urban)an environment,
    the more likely you are to be able to capture the wild yeast.

    And that having a bunch of organic grapes sitting near your starter never hurts ;) evidently they harbor wild yeast.
    If you are in a rural area there are even more wild yeasts to capture, but right now they are being over run by the pollen!

    Actually, studies seem to show that most of the wild yeast comes from the flour you use, not your surroundings; so you don’t really need to worry too much about being in an urban environment, finding wild grapes, etc. (though the wild grapes are a nice touch, and certainly wouldn’t hurt, as you say). Hope you’re not enduring hay fever with all that pollen around! PJH

  11. erie

    I must be doing something wrong. I have the starter in the crock, the rim is not as nearly as clean as in your pictures. I never throw anything out! I just feed (and let sit for 1 -2 hours depending on my schedule) and then use 16 oz for the Sour dough rye bread from your website. Feed again to make up for the double amount of taking out. It is not really sour, I would like it to have more pronounced sour flavor, on the other hand my family loves it this way. How can I get my rim to look cleaner? Take everything out, wash the crock and then put it back?

    Erie, yes, to get a clean rim, take the starter out, wash the crock, and return the starter. BTW, the crustiness on top isn’t hurting anything, as far as your starter is concerned; but if you don’t like it, feel free to give the crock a good going-over periodically. For more sour bread, try letting the shaped loaves rest overnight in the fridge. Oftentimes, the sourness of the bread isn’t contingent on the sourness of the starter so much as how you handle the dough; dough that’s chilled will allow the yeast to give off more acetic acid, which is more sour (think vinegar). If all else fails – try adding 1/8 to 1/4 teaspoon sour salt (citric acid) to the dough, which totally ramps up the sour flavor. PJH

    1. Pat Babcock

      Acetic? I think you’re more interested in a lactic acid profile. A good starter has both yeast an lactobacillus – both omnipresent in the wheat husk.

    PJ – just in time! My husband and I are moving into our new home this weekend (finally!!!!) and the kitchen is so much bigger than the one in our apartment (you’d think that kitchens in houses are bigger than the kitchens in apartments but you’d be wrong – one of the homes we looked at had a kitchen the size of my laundry room. We left quickly.). I’ve been wanting to try out a sourdough starter for months now but knowing we’d be moving, I decided to wait. I really appreciate all the ideas and extras from not only you but in the comments as well. I hate wasting food so the thought of simply throwing away the starter was a bit of a drawback for me. Thanks again for all the help and hints!! :)

    Well, welcome to your new home – wish I was there to bring you a loaf of bread and some salt, which is a traditional way to welcome someone to a new home (in Eastern Europe). Anyway, the very best of luck with your starter – have fun! PJH

  13. "J. J."

    PJ thanks for the great article. You mention in a comment that you use the discard in recipes that call for flour/liquid. I know it depends on how thick or thin you keep you starter, but do you have a rule of thumb for how much you would use to substitute water and flour in a recipe? I.e., if a recipe calls for a cup of water, could I substitute a 1/2C of unfed starter?

    J.J., I figure starter is just about half liquid and half flour by weight; I realize as it ages the liquid starts to creep up, percentage-wise, but it’s usually not critical enough that I worry about it too much when adding starter to a recipe. So, for any recipe using flour and water, you could use 1 cup of starter – which would be 4 ounces water (probably more like 5 ounces), and 2 ounces flour. Reduce the flour and water in your recipe by those amounts if you want to sub the starter. Does that make sense? PJH

    1. love

      Your starter works perfect for me. One time my bread doubled in 2hrs!
      What percenetage hydration is this starter?
      What is the typical ratio (stater, flour, water) for making bread?
      thank you

    2. The Baker's Hotline

      Our starter is a 100% hydration starter! However, I can not say there is a “typical” ratio for baking bread, it really depends on the type of bread you are making and the flour you are using. Please feel free to take a look at our recipe section, we have plenty of breads that use the sourdough. Jon@KAF

    I got the KAF starter last year and I am happy to report that the bunch of lactobacilli from Vermont is still bubbling happily here in this foggy city. As much as I search for new ways to use the ‘to be discarded’ starter, I have to throw some away from time to time. (They go to the worm bin. I still feel it’s wasteful.) I did bread and pancakes and crepes, of course, and even omelets. ( I’ll try it in muffins next time. Not sure about sourdough cake though.) For preserving, I wonder if the matured starter could be frozen? A baking book says the starter should be emptied out and the crock be cleaned periodically. Is this really necessary?

    Glad to hear it, Anne. Sourdough omelets – now that’s a new one! And trust me, the sourdough cake is wonderful – you’d never know it included starter. I think you could freeze starter, so long as it wasn’t kept below 0°F, since yeast dies at around that point. And, I don’t see why you need to clean your crock; unless you have trouble with unfriendly bacteria and spoilage, I don’t think it’s necessary. PJH

  15. tlvdatsi

    Is the yeast missing in these instructions, or is it not necessary? Color me confused! :-)

    There’s no added yeast in this starter; leavening comes from the wild yeast that’s in flour, and in your surrounding environment. It’s true, some starters begin with added yeast; not this one. It takes longer to get going, but if you follow the instructions you should end up with a very strong, active starter. Good luck! PJH

  16. MGW960W

    To Anne, on freezing starter:
    We were recently away from home for six weeks. Before I left, I took the loose tops off of the glass jars in which I keep my starters (regular and whole wheat). I covered the tops with plastic wrap rubber-banded around, and put them in the freezer. When we arrived home I took them out, loosened the plastic wrap and let them come to room temperature on the kitchen counter. Then I refrigerated them until I had time to feed. Worked like a charm. Don’t know about really long term storage. Good luck!

    1. Pat Babcock

      I recommend against freezing your starter. In yeast culturing, we generally “wash” the yeast, and suspend it in glycerin, which helps prevent the yeast cells from rupturing (if I recall correctly, the addition of glycerin exerts osmodic pressure on the cell walls. Don’t recall whether this reduces the water through the cell wall, or counters the pressure within the cell as the interior water expands – it’s been a while). Cells are mostly water, and you know what happens when water freezes, right? Aside from rupturing the cell walls via expansion, the ice crystals formed within can also be sharp enough to pierce the cell walls – even when glycerin is used, freezing drastically reduces the number of viable cells available in the culture. Your starter is no different. Again, as mentioned above, I store my starter through the late spring until the late fall simply by covering it and putting it in the back of the refrigerator. Yes, some yeast is lost to autolysis; however, due to the reduced temperature, the losses by yeast cannibalizing each other are far less than would be had I frozen the starter instead.

  17. Brenda in Irving

    I’m curious as to how to “wake up” the starter after you’ve put it in the refrigerator. I have a good idea but I’d sure hate to mess up after all the time involved in getting it started. This is definitely my summer project in the kitchen. Can’t wait!

    Brenda, check out our maintaining your sourdough post. Good luck! PJH

  18. RikkiMama

    In 2009, Debra Wink, a member of the King Arthur Baking Circle and microbiologist, experimented to find the best way to “fool-proof” making a sourdough starter from scratch. She found that using unsweetened pineapple juice for the first two feedings created a lower pH environment which helps the right bacteria and yeast to grow. (You can find her detailed research and instructions on the Fresh Loaf website.)
    I followed her method to create a vigorous and healthy starter almost 2 years ago. It’s still going strong.
    If anyone has problems creating their starter using water, consider trying unsweetened pineapple juice for the first two feedings. That may be the key to your success.

    We (the education team at KA) met with Debbie a few months ago, at the start of the project that ended up spawning this blog post, among other content pieces (yet to be published). She was an incredible wealth of information, and this post incorporated much of what she said. There are so many different ways to create your own starter; the pineapple juice method is one, this is another, and there are many more out there. The important point about baking with sourdough is – stay loose. Be flexible. There’s no one right or wrong way where sourdough is concerned… whatever works for you is good. Thanks for posting this info. here – the more we all share, the better! PJH

  19. Anne

    I want to thank MGW960W for the two helpful comments here: first the formula of 4 oz. unfed starter = 2 oz. liquid + 2 oz. flour, and how to let the starter (and myself) take a vacation. (Starter in the freezer; me, somewhere else!) This KAF site is a great place for anyone who wants to bake. (Best pancakes and pretty good chili recipes, too.) Picking up nuggets of good tips here and there, I suspect I am becoming a better baker?

    Anne, I suspect you are! I love how we all learn from one another here – PJH

      To be safe, I would double up on the starter and put half in the freezer and half in the fridge when on vacation. Then keep the one that seems healthiest. Not based on any experience I have, just a thought in case the freezer is too cold.

    Anne, you are most welcome. I’m really pleased to be able to pass on tips to a fellow baker, since I’ve learned so much from the people at KAF and from this blog.

    Since when is 4 ounces equal to 1 cup? Otherwise and excellent process. The rye flour is critical. With out it,, the flavors are not the same.

    Hi. Measurement by Volume and Weight are not the same. Here is the conversion chart. how you measure can make a difference in weight as well. Here is how we measure flour in all of our recipes. Frank @ KAF.

    Jack, people are often confused by weight. A cup of water weighs 8 ounces; but a cup of flour only weighs about 4 ounces. So long as you remember to feed your starter wequal amounts flour and water BY WEIGHT, you can’t go wrong. And, thanks for your feedback about rye flour in the starter. Sourdough, like all living creatures, can take many different shapes and characters. No right, no wrong; as always, we celebrate diversity! :) PJH

    1. Jim

      I’m just putting my starter together on the 1st day. I have added 4oz (1 cup volume) whole wheat flour with 4oz. (1/2 cup volume) water. This is way too thick. What am I doing wrong?

    2. The Baker's Hotline

      Your whole wheat flour may be particularly dry. Please just stir in a little extra water.~Jaydl@KAF

    Fellow bakers – if you are thinking of keeping a starter, splurge on the adorable KAF starter crock – it is very worth it! It makes me happy every time I see it in my fridge and reminds me to get another loaf started!

    I have my crock in the cellar fridge – that way it’s not looking at me and making me feel guilty for not feeding it EVERY time I open the (upstairs) fridge, but it does make me pause when I get my drinks down cellar… Anyway, sourdough is amazingly forgiving, don’t you think? All it needs is food and drink every few weeks, and it’s ready to make anything from bread to chocolate cake (actually one of my favorite uses for starter). Enjoy, Sara – PJH

  23. Sandy

    You say to use no more than 1 cup of the starter but I have your cookbook where your recipes call for 2 to 2-1/2 cups starter in each. How will I ever be able to make this if I can’t take more than one cup of starter?

    If you read the next post, Sandy, maintaining your starter, you’ll see how to build its volume. It’s fairly simple; either increase the amount you feed just before baking, or just feed without discarding for a few feedings. Good luck – PJH

  24. duhneece

    I worked dilligently to feed and nurture my starter all week. Today was finally day number 5 and when I uncovered my bowl, I discovered mold growing on the flour stuck to the side of the bowl, eek! What has gone wrong? I am very hesitant to try to get another starter going. Help!

    Sorry to hear of the difficulty. This sometimes happens. The only thing to do is to empty the container, wash and scald it, then begin anew. Frank @ KAF.

    PJ, the reason the Trader Joe’s yogurt did not drain properly is because you used the “European Style” yogurt (your photo). It’s soupy to begin with. I was at TJ’s and wanted to try the yogurt, plain, full fat, and organic. The European Style was the only quart available. Bought it. Returned it. Full refund. (TJ is very good regarding refunds; even if the customer just complains and has nothing to return.) The dairy crew person said that there is another organic, TJ yogurt, without the European designation, and it’s thicker, the American style; the type I wanted and expected. The reason I now use the full fat milk and yogurt is because one of the health newsletters I receive stated that in removing the fats essential enzymes are also removed. At my age, I need all the help I can get.

    Nellie, thanks so much for the tip about European-style yogurt; that was all I saw at my TJ’s. Next time I’ll ask the manager. And thanks for the information about full-fat; I’m getting to that “at my age” point myself! (If I could move this post to the Greek yogurt blog I would, but I don’t have the administrative capability; sorry!) :) PJH

    I am having a blast with this! My family is thrilled with all the baking that the cast offs engender. I am mining all the sourdough recipes on the site trying to keep up!

    Thank you so much! My family thanks you too! ;)

  28. "Dawn DeMeo"

    Ugh! I knew I must have misread something. I am on day 4 of my starter. I kept thinking at each feeding, how does discarding 4 oz of starter and adding 4 oz each of water and flour in any way maintain the total volume? I’ve been growing it in a 4 cup measuring cup, and as of this morning’s feeding there is not enough room for it to double. I reread and realized my mistake. Only the first time do you discard 4 oz. Every other time you discard all BUT 4 oz. DOH! Or rather DOUGH! I’m happy to say that, despite the extra volume, those yeasty beasties are thriving. I must have a lot of yeast floating around my kitchen from baking bread all the time. Well, looks like I’ll have a lot to discard tonight. Or a lot of pancakes, waffles, etc. to make. :)

    Thanks for sharing your learning opportunity for all sourdough bakers to learn from! Happy (sourdough) Baking! Irene @ KAF

  29. myriamdesilva

    This is my very first attempt at making my own starter, will also be the first time baking with starter.
    The first two and half days were fantastic. The starter was very active, doubling like you said it would, smelled just as described. I was so excited and proud of myself. Well, I did the second feeding on day three and the first feeding on day four (today). I have noticed that the activity has decreased a lot, and I mean a lot, the smell is not as pungent either. There are some bubbles but not the mountain of bubbles like day one and day two. Did I do something wrong? Will it get active again? I’m weighing out the amounts and checking off each step as I go.

    A reduction in activity is normal at this phase. Sounds like everything is going just fine. Frank @ KAF.

  30. Emily Bussenger

    A friend gave me a starter that should be fed every 3 to 5 days. It uses sugar,potato flakes,and warm water. I have used it with KA bread flour for months and have great results. Did I miss something in the info. about the different Sourdough recipes; there is no sugar in the starter or in making Nutty-Fruity Sourdough. No sugar is good. Please explain. I should be able to use “My” starter with your recipes right??? I’m going to give a try.
    Thanks, EmilyYou are referring to an “Amish” type starter which tends to be sweeter, and is not a sourdough starter. Our “sourdough” recipes are written for a true sourdough starter which contains sourdough culture, flour, and water. There is no sugar added in a true sourdough starter. Betsy@KAF

  31. Jacoba

    I can’t find K.A. unbleached all-purpose flour at stores around my house. Would you suggest K.A. unbleached BREAD flour or another brand’s BLEACHED all-purpose flour for day 2 and beyond? I don’t know if the chemicals in the bleached will affect the growth of the starter? Thanks for this tutorial – can’t wait to try it!

    Go for the King Arthur unbleached bread flour – increase the water by 1 tablespoon (beyond what the recipe says) each time you feed it, and you should be just fine. Good luck, and enjoy! PJH

    1. Jerry

      Unless there’s no other way around it, ONLY use KA AP flour. I’m serious about this. Ail order if you have to. The starter should be AP-based due the protein content. KA is far, far (did I say “far”?) more consistent than a brand like Gold Medal, whose content can and does change based on what part of the country you’re in. If shipping is an issue, wait for the shipping discounts, and/or buy KA AP flour in the 10- or 25-lb. bags.

  32. Kathy B

    I just came back from San Francisco, so of course I am trying to make a sourdough starter. How crucial is it to start with whole grain flour? Mine is four days old, and I started with your bread four. It is bubbling after feelings, but not growing.

    Whole Grain flour is “better” for this, but not essential. From your description, it sounds like your starter is established and just needs regular feeding to be set for baking. Frank @ KAF.

  33. pwcross

    So, I’m on day 5 of my starter, and while at eat feeding (every 12 hours), its texture and flavor and smell have changed, its volume doesn’t really seem to be changing. It’s certainly not anywhere near doubling. Any thoughts? It’s certainly warm in my kitchen, being California in summertime. I’m using fine whole grain flour. Thanks!
    If the starter is thick like a pancake batter and bubbly, you are on the right track. If it seems thin and inactive, you may need to add some flour. Be sure to discard in between feedings. Any further trouble? Give us a call on the hotline- 800-827-6836. ~Amy

  34. Stephanie

    So I am on day 2.5, and my starter seems SUPER active. I fed it last night (24 hours in) and this morning it had at least doubled, maybe more so, and was very bubbly. I went ahead and gave it another feeding this morning, but I’m wondering – is that it? Is it ready? It seems early in the process, but I’m in Texas so my house is a little warm this time of year, and I do a lot of baking. If it’s doubled this afternoon, should I go ahead and get ready to store it in the fridge?

  35. godivalocks

    So, I am on day 7 of my starter, and have been religiously feeding it every twelve hours with the correct amounts. Like another poster, my starter does not seem very bubbly on top, nor does it seem to be doubling. The temp is around low to mid 70s in here. The first day, I use KA white whole wheat to get it started, and it was nice and bubbly and doubled after sitting for 24 hours, but after I got to the point of doing the twice a day feedings, that disappeared. Now I have a pancake batter consistency with few bubbles on top and no doubling.

    The only thing different I did in the begining is that I mis-read the instructions and started with 1 cup of water and 1 cup of White Whole Wheat flour. It seemed to like that. Then I re-read and realized my error and went to the 1 cup flour and 1/2 cup water after the discard.
    Try discarding half of the starter before your next feeding and use a rye flour to feed for a day or two. Be sure to discard before every feeding! ~Amy

  36. CHRISR

    Hi, I am making your sourdough starter using organic rye flour that I’ve had for a few years. I have made it exactly the same way two times now and both times, with the help of my heating pad on low (great tip by the way), it looks textbook perfect except it develops an awful nasty smell after the first day. Even after several days of feeding it white flour, it’s still nasty. Other than that, it looks like healthy sourdough. I am using filtered water and a clean plastic container.

    I’m afraid to try it because it doesn’t smell right. (I’ve made starter before and know what it should smell like) Any ideas what my problem is? By the way, at the same time, I revived your 250 yr.old starter using the same white flour and it didn’t smell bad at all.

    Thank you.

    Chris, if your organic rye flour is a few years old, it’s no doubt rancid, and anything you make with it will smell bad – and taste awful, too. Please discard that flour and buy some new – any opened package of whole-grain flour will go rancid after a few months at warm room temperature, or 6 to 9 months or so in the freezer. I’m betting that’s the problem. PJH

  37. CHRISR

    Thanks PJH!! I was wondering, but wasn’t sure because I’ve never begun a starter with rye. I never thought about whole grains going rancid. I’ve read online about folks who oven can grains,beans,etc. for long-term storage. I just never made the rancid connection, silly me.

    I mentioned using a plastic container. Do you think that container is contaminated and unusable now that I’ve made this nasty concoction?

    Thanks again.
    Hi Chris,
    Best to go with a new container at this point, just to be on the safe side. ~ MaryJane

  38. Naomi

    I’m on day 5 or so. My starter is very viscous, almost gluey. Is there something I should be doing differently?

    Thank you!
    It is fine Naomi. Just add more water or cut back on the flour a little when feeding. It may mean you are measuring a heavy cup of flour. 4 oz. of flour and 4 oz. of water or 1 cup of flour and 1/2 c. of water. Take a look on our site for how to measure flour. Elisabeth

  39. smichik

    I’ve been nurturing my starter since day 1 and following all instructions precisely and I’m currently 8 days in and I’m not seeing my starter double in size. At first I thought it was too cold in the house (69 degrees) so I tried leaving it in the oven with the light on and then I started thinking it was too warm in there! I found a spot in the house thats about 75 degrees so I’m trying this spot. Any ideas??

    I had a lot of trouble getting my starter to grow, as well, until I ramped up the heat. I found it really needed to be above 70°F to grow well, so hopefully that 75°F temp. will do the trick for you. Good luck – PJH

  40. christinajieun

    I mistakenly used ww bread flour instead of ww flour in my starter for the first few feedings, but it seems to be active and doubling as normal. Is there any difference in using the two different flours for the starter? Another way of asking the same question: does the protein content in flour affect the starter? And if I switch over to regular ww flour, will it change anything?

    Christina, I’ve never heard of whole wheat bread flour, so not sure what you were using. But if it’s doing well, then hey – the proof is in the pudding! Er, starter… We don’t advise using whole grain flours for anything beyond the very first feeding – unless you plan to keep the starter refrigerated once it’s built. But as for protein content affecting starter – only in that protein content changes the liquid/flour balance, so the higher protein flour you use, the (slightly) less water you’d want to use in your feedings. Good luck – PJH

  41. Toujourscoeur

    Wow. I am so glad to have found your site. You certainly have the easiest instructions. I am on day three. I’m very optimistic. Day 1 I mixed 1 cup whole wheat flour with half cup water. I formed a thick dough and was hard to incorporate all the flour, so I added a little more water. This gave it a stick dough texture. I figured I would wait and see what it did. Day 2 all it had done was form a thin crust on the top. I just stirred it, but got side tracked and forgot to feed it. Day 3…Wow…I came home from work today and it had already doubled! I stirred it down, split it into two containers. I fed one as instructed with all purpose flour and water. I fed the other with only wheat flour and water. I will keep the wheat in the fridge as instructed. The wheat mix still comes out much thicker. Should I just go with it and see what it does or should I increase the water in the all wheat mix? Thanks again for the info and I cant wait to try the pancakes with discard starter.

    I’d say increase the water a bit; maybe the grind of your whole wheat is a bit different, affecting the absorption. It’s just easier to work with a starter that’s a bit more “pourable,” in my opinion. Best of luck – sourdough baking is certainly an interesting process (and yields tasty results, once you get the hang of it!) PJH

  42. Virgilio

    Your instructions above recommends having an average room temp of 70f. However, in the part of Asia I am in, the average room temperature is between 86f to 91f. Would it be to warm to even try making sourdough bread at home? Or should I stick the starter in the fridge instead? Or maybe you could recommend other timing/schedule?
    You can definitely place the starter in a cooler place, and use cold water too. That will help slow down the starter so that it doesn’t overferment. Our bakers use ice water in the doughs here during the summer months. ~ MaryJane

  43. Kevin

    So I have one quick question. I’m about half way through day 3 and my starter is already growing unbelievably. And I’m worried about its size. Here’s my question: On day 1, I put in 1 cup whole wheat flour and 0.5 cups water. Great. On day 2, I tossed half of it. This means that the remaining half consists of about 0.5 cup flour and 0.25 cups water (before adding to it). Then, per the directions, I add 1 cup flour and 0.5 cups water. So this new mix contains ~ 1.5 cups flour and 0.75 cups water. So, even if you ignore growth, the size of the starter is getting bigger. Is this correct? Or are we aiming to keep the size of the starter the same? In other words, do we add just enough flour to the starter, such that the sum is one cup? This isn’t entirely clear to me. Your help will be much appreciated.

    The key with sourdough is to keep the ratio the same with every feeding: 1:1:1 by weight of starter, flour, and water. I highly recommend measuring by weight if you have a scale (Also, baking by weight can be much more precise than by volume). So, for your starter, if you want to keep 12 oz on hand (8 oz to use in a recipe and 4 oz to feed without making extra), measure out 4 oz of starter ( a heaping half cup) then add 4 oz water (a half cup) and 4 oz of flour (a scant 1 cup). If you can figure out how much you’ll be baking with consistently (many of our recipes call for 8 oz of starter, so we ensure that there is 12oz of fed starter once it gets going, then keep 4 oz to feed after taking out the 8 oz to bake with), then you can re-calculate how much starter you’ll need once you feed it a few times if you keep the starter in the fridge (and feed it once a week!), being sure to follow the 1:1:1 ratio. For further help, I recommend calling our Baker’s Hotline: (802) 649-3717 Best, Kim@KAF

    HI King Arthur Baking Circle,
    I’m so thrilled with all the very helpful information and tips. I’m brand new to baking Sourdough bread and I’m on day 2 of my first starter. I have read all these comments over and over to make sure I haven’t forget or miss something, I do have one ? about it. I did my first feeding today and my starter is very thick, should I add a Tbsp or 2 of water?
    Thank-you for any help with this. Can’t wait to eat my first slice.!!!!!!

    Kim, just let it be and see what happens; sourdough does tend to thin out over the course of its feedings. And next time you feed it, if you’re able to measure your flour by weight, that’s the most accurate; if you don’t have a scale, make sure to measure your flour by the sprinkle and sweep method, OK? Good luck – PJH

  45. Joy

    Hi, I am just getting ready to begin day two. I have a few bubbles, but the top of my starter looks a gray/green color. Is that ok? I used your unbleached white wheat flour. I don’t want to use it if it has picked up something harmful, but I’m not sure if it has. It’s not as white and sticky as yours either. It is more the consistency of bread dough. Am I doing this right?
    The starter should have a consistency similar to a thick waffle batter. If yours is taking on more of a dough consistency, then it has too much flour. Read more about measuring flour here. Also, it should not turn color, especially so soon in the game, so my advice is to start over. Please give our baker’s hotline a call if you have any questions along the way. ~Amy

    I began developing my starter with these instructions about 3 weeks ago. It has been a wonderfully fun process. My starter did what it was supposed to do, and after the first week, I was able to refrigerate it. Since then, I have given three starter babies away to my mom, sister, and aunt. I printed out “birth certificates” for them with the date, Mom’s name (Momma Heater, since she was born on top of my water heater), directions, a place for the baby’s name, etc. It sounds dorky, but my family loved it, and I have thoroughly enjoyed it as well. I appreciate so much the detailed directions you provide here and the chat service as well. You have been most helpful in so many ways.

    My favorite recipe so far is the sourdough pizza crust. It rises beautifully and is a great use of the discard. I made some for a friend today, and she was very pleased. I’m fairly new to baking with yeast and definitely a novice with sourdough. I am curious how the starter will change with age. Will the flavor be different? It is quite mild now. I’m going to begin the sourdough English muffins recipe tonight and refrigerate the dough and see how that affects the flavor.

    I think the best part of this experience has been finding something very new to me related to the culinary arts. I wouldn’t call myself a master chef, but I am rather experienced and do well with recipe adaptations. Working with yeast and a sourdough starter have challenged me, and I had to start over as a beginner as far as following directions, watching videos, reading reviews and the blog, and learning from successes and failures. Again, thank you so much for making this process easier and helping me be a success at something very new and different. You truly are a wonderful resource.

    What a great idea to give out birth certificates with your starters! They really are like children, aren’t they? To answer your question, over time your starter will develop a stronger, more sour flavor. Also, sourdough bread recipes really excel when fermented for a longer period of time, the flavor just can’t be replicated with a short rise. We are happy to provide as much help as we can, but it sounds like you are becoming a sourdough master already!-Jon

  47. 4bankie12

    I began my new adventure with starter 3 days ago. I have been feeding it every 8-12. I have seen just a few bubbles and a little liquid on top. This morning when I fed it was a little foamy. The consistency is like pancake batter. I have not seen any volume change yet. Does all this sound like it’s suppose to? I also moved it to the oven with the light on, l thought my kitchen maybe too cool. Any thoughts because I don’t know what to look for!! Thanks!

    It will take a few days for the starter to really take off. I would give it a few more feedings to see how much stronger your starter can be. This is a great picture of what starter should end up like by the end of the process:×450.jpg Finally, the volume of the starter will rise and fall as the yeast feeds (when it starts to fall back down, that is a sign to feed it again before the yeast lose their activity. Persist and I am certain you will have zesty, vigorous starter soon! Kim@KAF

  48. Gabelous

    Here’s a question, and probably a problem. Been working on my own starter but there is one parameter I failed to consider, and that is an air purifier. Logically the science is the flour/water mix is supposed to attract the proper microorganisms to settle and feed and multiple, or rather yeast and lactobacillus form a self-sustaining, symbiotic relationship.
    Given this, am I correct to assume the air purifier may in fact be nabbing the very microorganisms I am looking to attract? I live in a medium-sized apartment so there is little chance I could isolate the two.
    Also I know the starch from potatoes (and the the water they are cooked in) tend to have a knack for giving yeast ideal food to eat. Could one add either such water or even potato flakes or flour to a starter or would that simple “over-feed” the yeast and they would become sluggish and not up to the task of leavening bread?

    Great questions! It is possible for an air purifier to limit the amount of yeast available to a starter; purifiers with UV lights often kill most yeast (and bacteria and mold). As such, it is strongly possible that you will struggle to begin a starter in your home: however, you could likely use air from outside to help get things going. Once the yeast are cultivated, it’s a matter of keeping them alive (with proper feedings). As a rule, yeast love the nutrients in whole wheat or rye flours–potato flour may as well, but I am most familiar with wheat and rye. You are welcome to use 50% of either flour when you feed the starter to encourage the yeast to grow. Finally, to get a starter going, you can certainly place the bowl of water and flour outside for an hour initially and then see if that “traps” any yeast cultures. Otherwise, you are welcome to persist in your home, it just might take a little longer! Best, Kim@KAF

  49. Tammy

    Would it change anything to start with 2 ounces instead of 4, and then maintain 2 ounce flour/water feedings? The ratio would be the same, but the volume (and discard) would be less. I’m just wondering because this seems like a lot of starter for only 2 people, especially if I’m going to be using the discard in recipes. I guess my question is more about if a smaller starting volume is ok or if it will change the ph or the growth of the yeast. Thanks!

    Tammy, I believe the smaller volume would be fine; though you’re going to be working with tiny little quantities, like saving just 2 ounces before feeding (1/4 cup). The process might be faster (or slower), I’m not sure. Give it a try, let us know what happens – PJH

  50. Gallupville_Doughboy

    I’m going to start my starter this weekend, but I can’t help thinking that “back in the day” before bottled water they used water out of a hole in the ground(a well)…just like I do…couldn’t I just use our well water?

    You certainly can use your well water. However, you will need to take into consideration that the various minerals in your water will change the flavor of your starter. Also, your starter will have a higher risk of possible contamination. If you see any pink or orange in your starter, it won’t be good to use.-Jon

  51. Alex B

    I have been following these directions for a week now, and I was wondering if it smelling like elmers glue is a bad sign?

    Please call our hotline, 800-827-6836 – this question deserves some back-and-forth dialogue to get to the heart of what might be happening. PJH

  52. Pamela

    Can you freeze the portion of starter that is to be discarded? With my work schedule, I know I won’t be making sourdough pretzels or waffles during the week, but would like to use it on the weekends, or beyond, if it will freeze. Any advice?
    Well, it is better to freeze starter after it has been fed to give it strength to survive. How about if you feed your starter on Fridays, and keep the unfed in fridge for waffles on Sat or Sunday? That would work out just fine. ~ MaryJane

  53. "Mary Elsbrock"

    I hope you can help – I just made a starter yesterday (not using this recipe, sorry!), and it has formed a crust on top.

    Is this normal, and if so, how should I proceed?

    Or do I need to start over? Thanks!
    As long as the crust is not moldy, you should just stir it back in to the starter so it can soften up again. Be sure to cover the vessel you are making it in so that too much air doesn’t get in. ~ MaryJane

  54. Nicole

    I started my starter per this recipe on Sat. March 2nd. I fed at 24 hours after the original start and then this morning(day 3) approx. 16 hours after the last feeding and not only had it grown some and is showing bubbles, it has a strong smell. I have very sensitive smell and so it was hard to deal with it. Not rotten I would say, just really strong and I guess ripe? Is this ok? Also I saved my discard from yesterday and was gonna mix it with the discard from today to make the pizza crust recipe on here because it had good reviews. Can i keep a small batch of discard in the fridge for use without feeding it? Just adding new discard?

    An active starter will be quite ripe, so you are doing fine! Keeping your discard is also okay, though I wouldn’t keep it longer than 2-3 days.-Jon

  55. Staci

    I think I’ve given my starter (about a week-10 days old) too much water. It’s more like a pancake batter. What’s the best way to fix the hydration? Should I just dump some flour in and mix to the right consistency? It was doubling but I screwed it up and now the bubbles seem to be popping right through and not raising the starter at all. I used a plain water/flour mix to start it and only used your regular unbleached bread flour (on a whim and with the assumption that it wouldn’t work). I had activity at around 24 hours, though. :)
    Yes Staci, it is fine to add more flour to thicken up the starter. The joy of starters is that they are very flexible and forgiving, and it takes a LOT to kill one off. ~ MaryJane

  56. Staci

    Should I wait until it reliably doubles again before I use/refrigerate it or is it actually alive enough in there to make some bread with but I can’t tell because its too wet?
    I think it would be just fine to use in bread now, and will be even better after it gets a bit more flour to chew on. :) ~ MaryJane

  57. imablessedmomma

    My starter has stalled out. I started it on Sat. March 2nd and it’s still not doubling. Today is March 13th. It’s active and bubbling, smells ripe and rises an inch or so in my 32 ounce yogurt container I’m using for this. I’m really wanting to make sourdough bread and I want the starter to be right for it.

    It sounds like your starter is quite active and ready to use. However, you do not want you to store it in a yogurt container because the high acidity of the starter will break down the plastic and leach toxins into your starter. We recommend glass or stoneware as a safe alternative. Betsy@KAF

      If you use a quart mason jar would you recommend using the canning lid which is watertight? Or maybe a looser cap that is not water tight? Just trying to figure out if it needs a little more fresh air than would be in the container. Obviously you open it up for feedings so new air gets in there.

    2. PJ Hamel , post author

      David, just screw the lid on loosely, without tightening it down; so it’s more a “cap” than a screwed-down, airtight lid. I’m sure it’ll be just fine. Good luck – PJH

      You would not want to screw the lid on if you use a mason jar, but just place it over the top to allow some air circulation. ~Amy

    Hi, thank you so much for all of your wonderful information. I have followed the instructions and my starter is really active but it smells like nail polish remover. Is this normal? It smelt very mild up until today.

    Sour dough starters will take on a rather strong alcohol smell over time, especially between feedings so this is pretty normal.-Jon

    Hi! I am making my starter for the first time ever…my family loves sourdough bread and the cost of buying it in the grocery stores is becoming prohibitive!
    At any rate, we live in the desert area of So. Calif. Is it possible for it to be too hot for the starter? Our home is kept at around 78 degrees F. in the spring and summer. However, my kitchen gets morning to noon sun and it can become nearly 85 in the area near my window. I am on day 4 and so far my starter is bubbling right along, but I don’t want it dying from being too hot either. Also, providing the starter keeps its’ progress up to day 7, can I then bake the sourdough bread recipe you have on the website here? How does one know if it’s ready or not? I’ve read all the great ideas and tips as well as the comment sections & they’ve all been a lot of help – I’m just a little afraid my bread won’t taste like the loaves we buy at the store…thanks!
    Your starter will activate more quickly in the constant higher temperatures and you will want to keep it in the fridge for any extended time when you are not using it regularly. Perhaps you should find a cooler place in your home at night for it to rest overnight on the days you are using it frequently. Once your starter is active and bubbly, it should be ready to use in the recipe! Have fun! ~Amy

    I thought that yeast only grew on free sugars, such as in grapes to make wine. To grow on starches, one needed to first cook, then add a malt (enzymes) to convert the starch to free sugars, then add yeast. No? What is the yeast consuming as it grows?

    Yeast is everywhere! It exists in the air around us all the time but can concentrate on the skins of grapes or other fruits. Yeast thrive on sugars of all kind, whether from wheat or malted barley or honey (and beyond!). What is important is that the yeast is fed in a proper regimen: always feed as much starter as you want equal parts by weight of flour/water: Example: weigh out 4oz of flour then add 4oz water and 4 oz flour. Then, once fed, the starter will take approximately 12 hours or so to go through the food if kept at room temperature. You should see the starter bubble and swell; when it starts to subside, that indicates the yeast are no longer feeding and are beginning to become inactive. This is where you will want to either feed them again OR begin baking! If the starter is kept in the fridge, it will go through the food in a week. I hope this helps! Kim@KAF

    Just to add to Kim’s great info. here, Mike – yeast is able to convert the starch in flour into sugar on its own, without any help from malting. It’s pretty self-sufficient, given the right atmosphere… PJH

  61. Amanda B.

    I started my starter yesterday. I mixed a scant cup of KA Whole Wheat flour and 1/2 cup then let sit for 24 hours.
    This morning, I took half out and fed it a scant cup of KA White bread flour and 1/2 cup water. The starter bubbled nicely and doubled (!!!) after about 6-7 hours.
    The next step was to wait another 24 hours, then on day 3 to every 12 hour feedings, but I’m afraid I’ll let my starter go hungry! It already seems so vigorous, (though I did read that this may be the bacteria causing this bubbling?)
    Do you think I should move on to twice a day feedings now, or just wait the whole 24 hours and follow the directions?

    The way to know when your starter has stopped feeding is to check its volume: when it stops swelling up and begins to sink back down, the yeast have ceased feeding so their activity has dissipated. You will want to wait until the starter has started to sink before feeding again or you will “drown” them in food. If you want to slow them down a bit, simply keep the bowl at a cooler temperature, about 5-10 degrees below that they are at now. For people who live at elevation, their starters rise unbelievably fast, so they often must keep their starters in the fridge to keep them from developing off flavors by fermenting too quickly. I hope this helps! Kim@KAF

  62. amytaylor61719102

    I’m happy to say that I have had good success with an entirely different sourdough starter recipe that called for equal parts unbleached white flour and spring water to be added each day without discarding anything. I used the tiniest pinch of commercial yeast to get it started, and I now have a beautiful, bubbly, thick starter that produces a nice layer of hooch every day. It has a lovely beer-ish smell, and a sharp, vinegary taste right from the jar. I am ready to bake with it, and I plan on making a multigrain boule (a KAF recipe!). Am I correct that the bread recipe is the same regardless of the starter used?

    Yes! I’m so glad you were able to make your own sourdough from scratch. Congrats! You can use any kind of starter with the bread recipe: just a healthy, active one will do the trick! Kim@KAF

  63. FAY M.

    I tried an unleavened bread recipe that had me leave just flour, water, oil and salt at room temperature for 40 minutes. the person i was making it for said i had to throw it out because it was left too long and already had leaven in it. I have searched internet all day and can find no confirmation. They all say pretty much leave the flour/water mix 24 hours, throw out half, etc. I see in one of the comments here that the discard can be used as pancakes or pizza dough. Does that mean it has leaven in it at that point? Also does anyone know a site that might give specific info on the stages of development as far as when it is technically leavened even though it may not be a starter for bread?

    Fay, if you’re talking about kosher/Passover dietary laws, your best bet would be to consult a site dealing with those issues; this site seems fairly easy to navigate, and gives leavening time as 18 minutes. Beyond that, scientifically speaking, the leavening process begins as soon as you combine yeast, flour, and water – it’s pretty immediate. And yes, the starter has leavening agents – yeast – pretty much from the day it’s started. Hope this helps – PJH

    Love your blog PJ, it very helpful to a very new newbie to sourdough baking like me! Problem (I think), I followed your directions to a T for the first few days (had it proofing in my oven with the light on) and it looks and smells great. I thought I was paying enough attention to the directions, but missed about feeding it twice daily for days 3, 4,5, then continuing for a total of a week. I got sick and got days mixed up and fed it twice daily for 3 and 4, then refrigerated it. Can it be saved and if so, what do I need to do? (I was actually feeling pretty proud of myself until I realized my mistake-go figure!). Have a great day, and thanks for any assistance.

    Sourdough is SO forgiving. I’m sure it’s just fine. Just continue with whatever recipe you want to use it in, feeding it before use; follow our sourdough maintenance directions for feeding. Have fun! PJH

  65. Mike

    I used this recipe starting about 2 weeks ago. After the first day i had significant rise with the whole wheat flour. Day 2 seemed to do ok but not great and while there was no rise there were some bubbles at the top. When I went to the every 12 hour feedings it seems like my starter tried to die. There were no more bubbles and no rise for almost 6 days. For the last few days all i have are 1-3 bubbles on the suface prior to feeding and no visible rise. How do i get this thing to grow? I have been at temperatures between 70-75 degrees the whole time and its smell has taken on a very viengary aroma but again no rise and very very little activity.
    Hi Mike,
    There could be a few different things happening, such as your water, etc. Give the hotline a call so that we can help troubleshoot in person. ~ MaryJane

  66. Chris

    I started making my starter 11 days ago. At first, everything was going well. Lots of bubbles and doubling of the volume. Then I started the twice a day feedings and everything slowed down. My house is a little chilly, so I have been putting the starter in my oven with the light on and turning the oven on every so often to keep it warm. The starter barely doubles in volume and there are very few bubbles. The smell is very ‘yeasty’, like white bread dough. And although I wouldn’t say it gets a ‘crust’, the surface of the starter is not fluid. The surface feels like kneaded bread dough- soft and giving but underneath the skin the texture resembles pancake batter. If you touch the top nothing sticks to your finger. Your photos look like your starter would be sticky. Also, once you break through this skin, there is a faint odor of alcohol. It’s gotten warmer the last few days and the temperature in my house has been in the upper 70s so I’ve let it sit out on the counter covered in plastic wrap. However, this doesn’t seem to effect its growth. Is this okay? Should I just give it more time because of the cool temperatures? Any suggestions would be great.

    There could be a few issues that are having an effect on your starter. I would give our Baker’s Hotline a call so we can speak to you in more detail about your starter troubles!-Jon 855-371-2253

  67. Katie

    I see to get started it calls for “4 ounces (1 cup)” flour and “4 ounces (1/2 cup) water” … Am I misreading this? 4 ounces is in face 1/2 cup, not 1 cup as mentioned for the flour. I’m going with the 4 ounces flour NOT 1 cup … so my flour and water ratio is the same. Correct?

    Flour is about half the weight of water: by volume, you need to measure nearly twice as much flour to equal the same amount of water. The measurement is correct: 4 oz of flour is a scant cup while 4 oz of water is a half cup. Kim@KAF

  68. Marilyn Achelpohl

    I am new to making a sourdough starter. My recipe said to put it by an open window with cheese cloth over the container. Since my air conditioning is on, I put it outside on day 1 and 2. It looks like the pictures but smells pretty strange. Is it bad to put it on the patio on summer days in the upper 80s? Should I start over and leave it in the house? Thanks for your advice.

    Marilyn, depends what you mean by “pretty strange.” If it smells sour/strong/vinegar-y – that’s how it’s supposed to smell. If it smells “rotten” and unpleasant, or has a pinkish tinge – then you’d probably want to start over. You also might want to check out our blog post on starting your own sourdough starter, for the best, most complete directions for this process. Good luck – PJH

  69. Frank

    I assume, I need to have some kind of yeast in this Starter. What kind and how much?

    No, no yeast, Frank. The flour will actually already hold some wild yeast spores, and with more in the air in your kitchen (they’re pretty ubiquitous), they’ll settle in your starter, and the liquid, flour, and warmth will gradually bring them all to life. PJH

  70. Rebekah

    I’ve been working on growing my sourdough starter all week and it looks happy. I’m making pizza crust tonight with the discard and hoping to make the sourdough multigrain boule tomorrow. I know I should keep some of the starter in the fridge for future use but I’m a bit fuzzy on the details? Do I feed it before I put it in the fridge? Do I feed it when it’s in the fridge? How long does it keep?

    Maintenance and feeding of your starter is all addressed on our Blog: A basic quantity of sourdough to keep is: 4 oz of starter + 4 oz flour + 4 oz water. Stir, let sit at room temperature for an hour or so to begin the feeding process, then keep in the fridge for 6 days and feed again then! Best. Kim@KAF

  71. Laura

    So, let’s say you began your starter… and the very first day – it did amazing. Grew quickly, got bubbly, etc. It remained that way for the first three days. I fed it once a day. Now suddenly, it almost seems as though it has died. One morning it has white foam on top. I scraped that off, mixed and fed again and now nothing is really happening. Not many bubbles, no rise, nothing. I’m pretty upset because I thought it was doing SOOO good at first. I even got a clear liquid after is settled the first two days which I was told was a good thing.
    This may be the kicker…. I live in Puerto Rico and our house is at a constant 85 degrees, perhaps maybe even a tad bit warmer since it’s summer.
    Can you give suggestions on what you think I should do with a starter in an 85 degree house? I really REALLY would like this to work! Thank you!

    Laura, I think it’s “full” – you’ve fed it, it’s happy, and it doesn’t need any more feeding. I’d suggest feeding it one more time, then baking with it; and refrigerating the remainder (once you’ve fed it). It should stay happy in your fridge for weeks on end. I like to feed mine once a week for optimal readiness, but it can definitely survive longer with no feeding… Hope this helps. PJH

  72. Caroline

    So I’m at the end of day 2 of my starter and it’s growing very quickly. Is this good, bad or wrong? It’s about to overflow out of my 3 cup glass jar. Should I stir it down? Discard some? Be worried it’s going to take over my kitchen???

    You can start with the smaller feedings, Caroline. By weight, it is equal parts of starter-water-flour (we like to do 4oz of each). By volume, it is 1/2 cup of starter, 1/2 cup of water, but a FULL cup of flour (water is roughly twice the weight of water). Then, you’ll want to feed it every 12 hours at that same ratio until it is ready to go in the fridge. I bet if you see plenty of bubbling activity tomorrow, you can give it one last feeding and store in the fridge until you want to bake–but be sure it gets fed once a week. You do want to be discarding any starter beyond the 1/2 cup that you keep to feed. Of course, we have many recipes that use it (we call it “unfed starter”), so be sure to peruse our recipe files and search for “unfed starter”. Happy Baking! Kim@KAF

  73. Warren Brooks

    What do I do to create a rye or wheat starter from the white starter?

    You will just need to feed your starter with either rye or wheat flour! Just make sure to increase the water by about 2-3 tsp when you feed it.-Jon

  74. Rajiv Gupta

    Hi, I mixed/kneaded KA whole wheat flour and half cup of water in a glass container but the dough looked very dry after mixing it so i added little more water and used my hands and kind of kneaded it. Is that ok or should i start over. It seems like it will always be kind of on the dry side with 1 cup flour and half cup water, is that true or should i not worry about it ?

    The reason your starter seems dry is most likely the way you have measured your flour. Adding a little more water is good, but take a look at this video and form here on out, measure your flour correctly. Your sourdough and breads will come out great.

  75. SgtSaunders69

    Your starter as seen in the photos here seems pretty wet and foamy. When I mixed mine up according to your recipe it was a somewhat heavy, though very sticky consistency, and upon checking it this morning before heading out to work (after 8 hours or so) it appeared totally unchanged from when I mixed it. It’s summer here and about 70 – 75 all day… so I’m wonderein g… Is that normal?


    It sounds like you may be using a little too much flour in your starter. We suggest to fluff up your flour and then spoon it into your cup. For other questions, please give our Baker’s Hotline a call so we can try to troubleshoot your baking problem with you!-Jon 855-371-2253

  76. Steve VanDeBogart

    I’ve tried twice with the same result – It doubles 12 hours after the first feeding, but grows less and less after each subsequent feeding. By day 4 or 5, it doesn’t grow at all. I discarded the first batch because I thought there might be too much chlorine in the Brita water, but the second batch with distilled water is acting the same.

    Help, I’m going through lots of flour with no result.

  77. Kitkat_lucky

    This is more of a nutrition question. Sourdough is thought to be super healthy. I want to give sourdough a try, but all I got handy is regular (bleached) flour and tap water. I know some people boil or “evaporate” tap water on a counter, and that’s ok. I know there’s a preference for rye or wheat flour, for its minerals and health boons. What I’d like to know is how much of the minerals carry on to the switch to all purpose flour, even after you’ve had a starter for a while?

    I know I’m a bit ahead of myself here, but I was wondering. Is it better to seek out wheat/rye, or would the overall benefit be the same? Any insight would be welcome. Thanks ahead of time.

    Whole grains are always better but not as easy to digest as white flour. The sour dough helps break down the gluten. I think it’s best to go ahead and use unbleached while flour even if you are using rye and whole wheat in your bread.

  78. Bess long

    I have been making bread for years with a starter which is fed with sugar, potato flakes and warm water. Although my bread is much sought after, I have too many air bubbles and air pockets in the finished product to suit me. Any suggestions? Thank you.
    Oh, I used to have a sour dough starter about 45 years ago. Made lots of French type bread but my husband’s favorite was the dollar size pancakes w/ orange syrup (melt 1 small can frozen concentrated orange juice, 1 stick butter, 1 cup sugar). As well as I remember I fed the starter the night before, put a half cup back, used what the recipe called for and threw away the rest. Your method seems more complicated.

    Please call our Baker’s Hotline and we can help to troubleshoot your bread!-Jon 855-371-2253

  79. filmsforme

    Please help. I can’t find a good way to dispose of my extra starter. It’s like cement so I can’t put it down the drain, it’s too messy for the trash can. I’ve tried putting it into gallon sized plastic zip bags left open a bit but they expand and I fear an explosion. What do people do with the extra from feeding everyday? I’m on day 8 and my bread didn’t taste so sourdough-y, more like a really good tasting bread, so I kept feeding the starter. Is there something that I can put into it to stop the bubbles and expansion when I dispose of it into the trash? Please don’t laugh. I love good sourdough and can’t buy it where I live so I have to get this done.

    I would suggest to give our Baker’s Hotline a call. We can go into more detail about what you can do about your discard and starter!-Jon 855 371 2253

    I think it’s great that you folks @ KAF support your customers and the entire baking community as a whole, down to the finest process and recipe. There is so much of a community and customer-service feel here that it is truly a class act! Thank you KAF.

  81. Audrey

    Can the sourdough starter be used for whole grain breads also, or just for sourdough bread?
    Yes, you sure may use the starter for whole grain breads. The majority of the dough will be whole grains while the starter is maintained with an all purpose flour. Enjoy! Elisabeth

  82. Abigail

    My starter is doubling in size in less than five hours; I started it less than 48 hours ago, so I’ve only given it two feedings so far. Is this normal? Does this mean that I will be able to use it to bake bread soon?
    Sounds like you have a great starter going. I would say you’ll be able to use it today or tomorrow and you should get a great rise. ~ MJ

  83. Paul gerhold

    Can you use bread flour in place of all purpose flour?


    Yes, Paul – you’ll want to increase the water you use by 1 tablespoon, to account for bread flour’s higher protein. Good luck – PJH

  84. glacierlily

    I was very excited to find this Zojirushi Bread Machine recipe for sourdough….. I loaded everything into my machine #BBCC-V20 and found that I cannot set my rise timers past 2 hours…… so I’m setting all three rises for 2 hours….. not sure how this will turn out. Has anyone else had this problem? Don’t know what I’ll wake up to in the morning.

    Sourdough is so very forgiving, I’m sure those three 2-hour rises will give you excellent results. If you have any questions, though, please contact our baker’s hotline toll-free, 855-371-BAKE (2253). We can help – PJH

  85. Joy

    I am new to the world of sourdough but have been excited to try it as I’ve been reading about the health benefits. I tried to make a gluten free starter simply using gluten free flour and water. I notice some fuzzy, moldy growth around the rim of the bowl where starter had splashed. Do I need to throw it out and start over? The recipe I used was from a different site and it was 1/2 cup water and flour. Not sure what to do from here. Please help!
    I would definitely discard the moldy starter and if you’d like, you can refer to my gluten-free sourdough starter blog for a new recipe and method. ~Amy

  86. Monica in Phoenix

    Hi everyone. I believe I have mastered the starter. It is rising and falling within an 8 hour period. It definitely is ripe.

    Here is my question though. After much reading and a few attempts with using this starter I have had marginal success in the outcome of the finished bread. I was thinking it has something to do with the density of the starter being used. The dough at the beginning is so wet and sticky is putting it lightly. The recipe in your Whole Grains Baking book page 285, Whole Wheat Muli-grain Sourdough Bread said that it would be springy and elastic and DO NOT INCORPORATE more flour into the dough. But I could have literally poured (and did) it into the proofing bowl. It said to knead the dough, impossible even with a bench knife. So, what is the issue, is my starter too thin even though ripe? Or am I being too literal with the directions? I baked it anyway after the long rises called for (about 3.5 hrs). The loaf did not Oven Spring so pretty much same size going is as coming out, a bit gummy but not bad, it had the traditional holes in the crumb. Taste was pretty good but not the outcome I was looking for. I would like to try this recipe again but have some fears. Also, I don’t have a banneton pan and used a colander with a flour sack towel and what I thought was enough flour in it. But to make the situation worse, it did not fall out but stuck to the towel causing the rise to be diminished.
    Sorry this is long. Basically, how does the relationship of the liquid in the starter relate to a recipe. Perhaps we have to dial the liquid in the recipe down a little? I find it hard to believe the dough should be so wet as to pour out to knead.

    I have created a starter from your recipe on line and have also purchased your bread book. I am an avid cake baker and have recently obtained a contract to start making bread for a local store. What is the best way for me to create a LARGE amount of fed starter? The store is wanted roughly around 200 loaves of bread a week. HELP please!!:)

    Stephanie, please call our bakers’ hotline, 855-371-BAKE (2253). They can connect you with someone who can help. PJH

  88. Shannon

    I have used this recipe and religiously fed it on time for a week. I have a nice aroma and consistency, but it does not seem to double with each feeding. I have bubbles on the top. Am I doing something wrong, or does it just need more time?

    The starter should rise, then fall – creating bubbles along the way. Sounds like you’ve been following the directions, we wonder if you used the optional sugar/honey as it would provide some food for the yeast? This may be a good opportunity to call the Baker’s Hotline at 855-371-2253 and we’ll chat about possibilities. Happy Baking – Irene@KAF

  89. John Johnson

    Did I follow the recipe correctly? 1 c. Rye and 1/2 c. water? After Day 1 my starter is still hard as a rock! All other research indicates that equal parts of flour and water shall be used. I’ll throw away and start again……
    The equal parts reference is by weight, not volume. So yes, 1 cup flour to 1/2 cup water is correct. ~Amy

  90. Laura

    Oh No! It’s day 3 – time to start the daily feedings – and I’m leaving for the weekend? What should I do? Feed once and put it in the refrigerator until I get home?

    1. bakersresource

      That is exactly what you should do. Feed and store in the frig for a few days. No problem! Have fun! Elisabeth

  91. Leanne

    I just made my starter with1 cup whole wheat floured 1/2 cup of water, it looks like a ball of dough and is hard. Should I use sifted flour?

    That whole wheat flour does absorb more liquid than all purpose flour, so simply add tablespoons of water until you get that pancake batter consistency. Happy Baking! Irene@KAF

  92. Nicholas Zindorf

    I have been using a starter for about 6 years. The recipe is from Nancy Silverton’s book “Breads From the La Brea Bakery.” Her method utilizes organic grapes with flour and water and makes excellent tasting breads. I am at the point where I make up my own recipes using the basic starter as a baseline leavening/flavoring element for baking. I especially enjoy making different kinds of bread using semolina flour and fresh herbs from my garden. This kind of flour is also much easier to work with and less messy. The issue I have about my starter is that when I store it in the refrigerator, the liquid that forms at the top begins to turn a dark color if I don’t use it for a long (say 1-2 months) time. I don’t know if this is unhealthy or not. I have continued making it without any ill effects to date. What causes the liquid to turn color and is it safe to use?

    1. The Baker's Hotline

      The liquid is changing color because it is slowly fermenting. The liquid is actually alcohol that is produced as your yeast is dying in your starter and it is completely normal and as far as I know has not been known to cause any issues. However, it can be removed if you have any fear! Jon@KAF

    1. MaryJane Robbins

      Yes, you can use spelt flour to start your starter. It is a different variety of wheat. ~ MJ

  93. Esther

    This is my first time making a sourdough starter, and I have followed your instructions and have been feeding my starter for about 10 days now. I keep my starter in a glass mason jar on a windowsill, lightly covered with plastic. My starter bubbles nicely, however I do not notice any increase in volume. I have tried waiting longer before feeding it, but that did not make a difference.

    I am living at an elevation of almost 8,000 ft, but have only been living here a few months and have no prior experience baking at high altitudes. Are there any adjustments I should make due to the altitude? I have made the sourdough waffles and pizza crusts with the discard, and it definitely has a sourdough flavor, I just don’t know why the starter is not doubling in size.

    Thank you for your help!

    1. MaryJane Robbins

      It may be that your starter is a bit too thick. Try giving it a bit more water than flour so that it is a little on the looser side. ~ MJ

  94. David P

    Hi I’ve been using your recipe for about 2 weeks now, but it hasn’t gotten thick. It has stayed somewhat watery like pancake batter. It smells good (a bit like bread) and has some bubbles in it. But I tried baking with it and got zero rise. I think it is too watery and is not “maturing”? How much water should I cut back to? Or what should the consistency be?

    1. PJ Hamel , post author

      David, it could be your starter isn’t warm enough. And it could be you simply have to add more flour with each feeding. Add enough flour that it’s a bit thicker than pancake batter, and then try to keep it someplace where it’s in the high 70s, temp-wise; a cooler house (e.g., below 65°F isn’t going to make your starter very happy. Also, if you’re baking with starter and not adding any commercial yeast, again, you need a warm rising spot; you need to give the dough a lot of time; and even then, sometimes your starter simply isn’t vigorous enough (and it sounds like yours isn’t). This is a situation where I think it would really help you to call our baker’s hotline, for some dialogue; call 855-371-BAKE (2253), and I think they can help talk you through this. Good luck – and don’t give up. You’ll get there! :) PJH

  95. Ron Gray

    I just realized the amounts you show in the recipe could throw some folks off…it thru me off. You suggest 4 oz (1 cup) of flour and 4 oz of water. You have 1 CUP in parantheses. The recipe is 4 oz which is a 1/2 cup. Am I missing something or is this a typo?

      Sorry, Ron, I’m not seeing where in the post we refer to 4 ounces of water as being 1 cup. Could you maybe count down the pictures, and tell me which one it comes after? Thanks – PJH

    It’s in your Day 1 description:
    Day 1: Combine 4 ounces (1 cup) whole rye flour (pumpernickel) or whole wheat flour with 4 ounces (1/2 cup) non-chlorinated cool water in a non-reactive container. Glass, crockery, stainless steel, or food-grade plastic all work fine for this. Here, I’m using a 4-cup glass measure.
    Day 2: Either way, discard half the starter (4 ounces), and add to the remainder 4 ounces (a scant 1 cup) King Arthur Unbleached All-Purpose Flour, and 4 ounces (1/2 cup) cool water (if your house is warm); or

      Ron, this is all correct, so far as I can see. 1/2 cup water weighs 4 ounces. 1 cup flour weighs 4 ounces. Is that where the confusion comes in, the weight of the ingredients not being what you expected? PJH

    Dear PJH,
    I apologize for the error of my ways…lol. Totally thinking in liquid instead of dry measure. I have been baking shortbread the past few days and after looking up dry measurements for a cup realized it was 4-4.5 oz. Will be interested to see how the shortbread comes out after weighing my flour. Thanks for the starter. In the process of brewing.

      That’s what I was figuring, Ron. It’s VERY confusing when you have in your head, “a cup is 8 ounces.” We all make that mistake at first. Good luck with the shortbread, AND with the sourdough! :) PJH
