I'm covered up with laundry, dirty dishes, and some baking for church today. Guess we shouldn't have made that spur-of-the-moment zoo trip this morning, huh?
After mixing all my ingredients I realized I had no baking powder in the cupboard. Deborah Buhr's "I Can't Believe This Has No Sugar" Cookbook produced a quick substitute:
1 teaspoon baking soda
2 teaspoons arrowroot
2 teaspoons cream of tartar
Mix and store in airtight container. Yield: 5 teaspoons
Use 1 1/2 teaspoons of homemade powder to replace 1 teaspoon called for in a recipe.
