Question: can you use baking soda for baking powder?
Answer: And remember that baking soda has 4 times the power of baking powder, so 1/4 teaspoon soda is equivalent to 1 teaspoon of baking powder. You can make your own baking powder at home: Sift 1/4 cup cream of tartar and 2 tablespoons baking soda through a fine strainer 3 times into a small bowl.
