what can you substitute for baking powder
For every teaspoon of baking powder called for in your recipe, youâll need just 1/4 teaspoon of soda to replace its leavening action. Youâll also need to furnish the necessary acidity, adding either 1/2 teaspoon of cream of tartar or a cup of buttermilk or soured milk to the recipe in place of sweet milk. Alternatively, add a tablespoon of lemon juice per cup of milk.
