Cream of Tartar Substitute – The answer is – there is not a good substitution for cream of tartar. If it is used along with baking soda in a cake or cookie recipe, omit both and use baking powder instead. One (1) teaspoon baking powder is equivalent to 1/4 teaspoon baking soda plus 1/2 teaspoon cream of tartar.
Subsequently, one may also ask, what can I use as a substitute for cream of tartar?
But if you don’t have it in your pantry and your recipe calls for it, just substitute fresh lemon juice or white vinegar for the cream of tartar. For every 1/2 teaspoon of cream of tartar in the recipe, use 1 teaspoon lemon juice or white vinegar. Add 1/2 teaspoon lemon juice per egg white.
