The taste of homemade marshmallows is unbelievably rich compared to the store-bought variety. And with the opportunity to flavor or shape them as you desire, who wouldn't want to try this fun treat? While dealing with the sugar syrup is clearly a job for grownups, spreading the marshmallow in the pan and cutting them out is one kids will enjoy.
3 packages (1/4-ounce each) unflavored gelatin
1 cup (8 ounces) cool water, divided
1 1/2 cups (10 1/2 ounces) granulated sugar
1 cup (11 ounces) light corn syrup
1/8 teaspoon salt
1 tablespoon (1/2 ounce) vanilla extract
crushed peppermint candies, peppermint oil, or espresso powder, all optional
confectioners' sugar, to sprinkle on top
Combine the gelatin and 1/2 cup cool water in the bowl of an electric mixer fitted with the whisk attachment. Combine the sugar, corn syrup, salt, and 1/2 cup cool water in a small, deep saucepan. Cook the mixture over medium heat, stirring, until the sugar dissolves. Raise the heat to high and cook, without stirring, until the syrup reaches 240°F on a candy thermometer. Remove from the heat.
With mixer on low speed, slowly pour the sugar syrup into the softened gelatin. Increase the speed to high, and whip until the mixture is very thick and has cooled to room temperature, 8 to 10 minutes. Add vanilla towards the end of the mixing time. This is also the time to add a few drops of peppermint oil, if desired, instead of vanilla extract. Or try 1/2 teaspoon espresso powder for a coffee-flavored treat. To use the crushed peppermint candies, which will tint the marshmallow pink and add flavor, stir the candies into the marshmallow mixture, leaving some swirls of plain white.
Spread the marshmallow mixture into a greased 9" x 13" pan (glass or ceramic is best). Use your wet hands to smooth and flatten the marshmallows. Sprinkle confectioners' sugar over the top, and let sit for several hours (or overnight) before cutting. Use a greased knife or cookie cutters to make squares or other shapes. Yield: about 100 1" squares.
