Hi, I'm about to make a sponge cake and realized I only have gluten-free baking powder. The cake is not gluten free. Does it make a difference?
What is gluten-free baking powder?
Baking powder is a combination of sodium bicrbonate and sodium aluminum sulfate, with, sometimes, cornstarch added as a non-caking agent. Where would gluten come from in the first place?
I suspect what you're buying is a manufacturer's way of capitalizing on the gluten-free mania.
