I was busy looking for a source that was guaranteed aluminum free, when I stumbled across this recipe in Super Natural Cooking by Heidi Swanson.
I have been using it for months now and love it. My baked goods rise beautifully and it's easy and inexpensive to make.
Here is her recipe:
*1 part baking soda
*2 parts cream of tartar
*2 parts arrowroot
Simply mix together. Swanson says this should last for a month, but I have had mine at least 6 months and it still seems to be working great!
