Sift flours together, and store in an airtight container in the refrigerator.
Use to replace gluten-containing flours in most recipes. If you're using it to make cakes, add 1 teaspoons xanthan or guar gum per cup of flour mix. For breads or pizza, add 2 teaspoons xanthan or guar gum per cup of flour. For cookies, latkes and other recipes, use no xanthan or guar gum or just add 1 teaspoons per cup of flour mix.
