I did add the “optional cornstarch” and used this for making muffins...it worked. Cream of tartar is expensive, so at least for me, this won’t be a substitute for buying a can of baking powder, but if you’ve run out and don’t want to make a trip to the store, just mix up a small batch of this recipe.
