substitute Flours and Grains

WHEAT FLOUR (one cup) GLUTEN FREE: Since no single wheat-free flour has all the attributes of regular wheat flour, the trick is to blend several wheat-free/gluten-free flours using final product texture as a guide.  a good basic flour that can be used in equal (1:1) substitution for regular wheat flours. Her gluten-free flour blend suggests:
bulletFor every 3 cups of flour, use 2 cups white rice flour plus 2/3 cup potato starch plus 1/3 cup tapioca starch well blended with the appropriate amount of xanthan or guar gum.
bulletAny additional protein that can be added (e.g., milk, egg or gelatin) helps offset the lack of gluten protein. 
bulletFor every cup of wheat-free/gluten-free flour, use 1 tsp. xanthan or guar gum for cakes, 2 tsp. xanthan or guar gum for breads or pizza, and 1tsp. or no xanthan or guar gum or most cookies.

NOTE: Wheat/gluten-free flour dough will be stickier, heavier and softer than regular wheat flour dough because there is little to no elasticity to the dough without the gluten.  For these reasons, use a batter beater, not a dough hook, to beat extra air into the dough and blend thoroughly.

ALL-PURPOSE FLOUR (one cup)
bullet1 cup all-purpose flour = 1 cup plus 1 tablespoon pastry flour or Wondra Flour (instant dissolve).
bullet1/2 cup whole wheat flour plus 1/2 cup all-purpose flour
BLEACHED CAKE FLOUR (one cup) 1 cup cake flour equals 1 cup (preferably) bleached all-purpose flour minus 2 tablespoons, and then add in 2 tablespoons cornstarch.  Combine.
SELF-RISING ALL-PURPOSE FLOUR (one cup) 1 cup all purpose flour, plus 1 1/2 teaspoons baking powder and 1/2 teaspoon salt is the published substitute to use for all self-rising flour. However, not all flour used is alike.

For example, White Lily self-rising flour uses soft-winter wheat. They said that their self-rising flour = self-rising cake flour, so use the substitute for self-rising cake flour, below.

SELF-RISING CAKE FLOUR (one cup) 1 cup cake flour with 1 1/2 teaspoons baking powder and 1/2 teaspoon salt.   
SELF-RISING CORNMEAL (one cup) Add 2 teaspoons of baking powder and 1/2 teaspoon of salt for each cup of regular cornmeal
WHOLE WHEAT FLOUR (one cup) = 3/4 cup all-purpose plus 1/4 cup unprocessed (raw) bran flakes or 1 cup all-purpose, but the results may not be as good.
WHOLE WHEAT PASTRY FLOUR (one cup)  Plain pastry flour, 1 for 1. If you want whole wheat, remove 1/4 cup flour and blend in 1/4 cup unprocessed (raw) bran flakes. Other than that, there is no good substitute for it -- some use cake flour, but I don't like the results. 
QUICK COOKING OATMEAL Do not use instant. You can pulse the old-fashioned oatmeal in the food processor to get smaller pieces so that it's just like the quick cooking oatmeal.
