Question: can u use baking soda for baking powder?
Answer: Yes, as long as there is enough of an acidic ingredient to make a reaction (for 1/2 teaspoon baking soda, you need 1 cup of buttermilk or yogurt or 1 teaspoon lemon juice or vinegar). ... Or, for a teaspoon of baking powder, simply substitute 1/4 teaspoon baking soda and 5/8 teaspoon cream of tartar.
