[OC] Home made baking powder
So, I know that home made baking powder is 2 parts cream of tartar and 1 part baking soda. Cornstarch is optional to prevent breakdown. I've been making this for 4 months and it works but could I use less?
What I'm curious about is that without the cornstarch, wouldn't the baking powder be substantially more potent? The ingredients on commercial brands start with cornstarch indicating that to be the primary ingredient.
