Wow, is that a mouthful or what. Anyway, I love the bread from The Whole Life Nutrition (I add eggs and end up making three loaves) and have found that making up a huge batch of the flour mix that she uses works just about right for many of the everyday things I like to do. I do exchange cornstarch for the potato starch. Works and that's what I have.
All Purpose Gluten Free Flour Blend
2 c millet flour
3 c sorghum flour
1 c sweet rice flour
2 c cornstarch
1 c tapioca starch
1 T xanthan gum
Sift all ingredients together and then whisk like crazy until they are throughly combined. Put it in a zip lock in the cupboard for whenever you need the mix.
