Baking Mix #2, Fat Free (Bisquick Copycat)

4 c Better for Bread flour
4 c Whole wheat flour
1/2 c bran (or wheat germ;
-but it contains more fat)
2 tb baking powder
1 tb salt
1 ts baking soda
2 ts cream of tartar
(½ c mayonnaise fat free-see below)

Mix all ingredients very well. For every 2 cups mix used add 1/2 cup fat free mayo... THIS REPLACES THE USUAL SHORTENING. (You can substitute applesauce, prunes, pureed squash or whatever you prefer to replace the fat free mayo.) This recipe may be made with all wheat flour or any combination. The mix works great in any recipe calling for a commercial biscuit/baking mix.
