Nope! You can use arrowroot powder instead. Use it at a 1:1 ratio in place of cornstarch.

These ingredients will store individually on your shelf for years. Once they are mixed together, the shelf life is 6 months to 1 year.

Absolutely! I go through a lot of baking powder with all of the from-scratch baking that I do. I always make the large recipe.
