This wheat-free baking mix is a mixture of several other flours that, along with the addition of xanthan gum or guar gum, approximates wheat flour.
1 part (28.5%) by weight white rice flour
1 part (28.5%) by weight brown rice flour
1 part (28.5%) by weight tapioca starch
½ part (14%) by weight amaranth flour
2–4% by weight xanthan gum (optional)
Combine all ingredients. Mix until very thoroughly blended.
Use the blend as a substitute for wheat flour, using the same weight of the blend as of the wheat flour; for example, if a recipe calls for 100 g wheat flour, use 100 g of this blend.
