I have been making my own bisquick for a couple years now. It is so much BETTER than the store bought.Here is my recipe real similar to the other one.
This makes a lot.
8 cups flour
1 1/4 cups Nonfat Dry Milk Powder
1/4 cup baking powder
1 tablespoon salt
2 cups shortening.
Combine flour, milk, baking powder and salt in a very large
bowl. Cut in shortening until it resembles coarse cornmeal. Store in tightly closed covered container in a cool place. Makes about 10 cups.
I also have a recipe using this mix for my biscuits and I double that recipe and I use up my mix and freeze the biscuits.
