No that is not my mad scientist. That is his influence on me in the kitchen. Imagine the horror that over took me when I realized that the baking powder that I was using, which had no aluminum in it, had corn starch in it. I knew that it took cream of tarter but what else so off I searched. After looking at several recipes some including arrowroot or tapioca starch which are not really needed here is what I came up with.
1 part baking soda + 2 parts cream of tarter or 1T baking soda + 2T cream of tarter
Other substitutions that I use:
Coconut flour and any nut meal.
Raw sugar, honey, real maple syrup
Raw sugar or coconut sugar
Butter, ghee, coconut oil
Have fun experimenting!
