1) Select a pie pan whose inside top dimension is at least 9", and whose height is at least 1 1/4". Preheat the oven to 325°F.
2) Make the crust by stirring together all of the crust ingredients, mixing till thoroughly combined.
3) Press the crumbs into the bottom and up the sides of the pie pan.
4) Bake the pie crust for 15 minutes; it'll start to darken in color a bit. Remove it from the oven, and place it on a rack to cool while you make the filling.
5) Whisk the grated lime zest and egg yolks at high speed of an electric mixer for about 4 minutes. The mixture will lighten in color and thicken somewhat, looking kind of like Hollandaise sauce.
6) Stir in the sweetened condensed milk, mixing till smooth. Beat at high speed for 3 minutes; the filling will become slightly thicker, and gain a bit of volume.
7) Add the lime juice, stirring just to combine. The mixture will thicken. Add lime oil to taste.
8) Pour the mixture into the crust, and return the pie to the oven. Bake for about 25 minutes, till it appears set around the edges, though still a bit wobbly in the center. The center should read about 145°F.
9) Remove the pie from the oven, and cool to room temperature. Refrigerate for several hours before serving. Slice and serve each piece with a lightly sweetened dollop of whipped cream, if desired.
Yield: one 9" pie, about 8 servings.
Hi Kenya- I think it sounds like the crust may have just been a little overworked, so next time you make it, I would recommend handling the dough as little as possible and being careful not to over-mix it when you are bringing it all together. In regards to the bitterness, if you used the larger amount of lime oil,you could try reducing that the next time around. However, I am guessing when you zested your limes, you may have gotten some of the light green or white pith which is very bitter. So, the next time around, I would recommend being careful to ensure that you only zest the very outer bright green part of the lime where the oils are found.
