what is a substitute for flour
We wanted to avoid refined white flour for similar reasons that we avoid refined white sugar. There's very little nutritional benefit left in refined white flour. Wheat flour is the typical substitute, but I had some pretty severe food allergies as a child and one of them was to wheat. So when Amelia came along we wanted to avoid exposing her to wheat for the first few years.
For the best results, use 3 cups wheat flour for every 1 cup of oat flour. If pastry flour is unavailable, substitute equal parts all-purpose flour and cake flour. Another alternative is to use 2 tablespoons of cornstarch for every 7/8 cup of all-purpose flour required for the recipe.
