I like this blend for sandwich bread, sandwich rolls and wraps.
1 cup brown rice flour
1 cup garbanzo bean flour
1 cup sorghum flour
1 cup arrowroot starch
1 cup potato starch
1 cup tapioca starch
1/2 cup amaranth flour or quinoa flour
1/2 cup teff flour or millet flour
Sift all ingredients together and store in the refrigerator or freezer. If you don't have arrowroot on hand, substitute 1/2 cup potato starch and 1/2 cup tapioca starch instead.
