True cream of tartar is created from the crust of wine casks, where it precipitates from the grape’s tartaric acid. You can create your own baking soda by combining ¼ teaspoon baking soda and ½ teaspoon cream of tartar.
Cream of tartar helps meringues for pies and other baked goods maintain fluffiness. It’s also good for cleaning copper cookware - just mix it with water to make a paste and rub onto your pots and pans. We also sell cream of tartar to kindergarten teachers who use it to create their own homemade play dough.
