And here is a recipe for Make-your-own-Bisquick, for anyone that wants it:
8 cups flour
1-1/4 cup pwdered milk (non-fat if you can find it)
1/4 cup baking powder
1 Tbsp. salt
2 cups solid vegetable shortening
In a large bowl, combine flour, milk, baking powder, and salt. With a pastry blender or two knives, cut in shortening until the mixture looks like coarse cornmeal and the shortening is evenly distributed. Store in tightly closed covered container in a dark, cool place. Use in place of 'Bisquick' in any recipe.
