I need cream of tartar to make a special apple pie,but I have none can you tell me the correct substitute I need a proper answer The pie is called cracker apple pie the crust is made of crackers

    Can you show us the recipe? I suspect any acid in the right amount will work for an actual apple pie. Is it mock apple pie, made with Ritz crackers, and no apples? If so, that calls for a LOT of cream of tartar, plus another acid (lemon juice). In that case, I would be nervous about any substitution. Certainly, don't try to substitute baking powder. That will throw the chemistry right off. – Jolenealaska Apr 1 '15 at 21:28
  • @Jolenealaska Totally agree. Follow up is needed from the OP for a definitive answer. – Cindy Apr 1 '15 at 22:49

Baking powder cannot be used as a substitute for cream of tartar.

Cream of tartar is used in recipes as a dry acid.

Baking powder has cream of tartar added to leavening agents that have a basic pH. Thus baking powder as a whole is not acidic.
