Flaky Pastry

5 cups all-purpose flour
1 tablespoon brown sugar
1/4 teaspoon baking powder
1 1/2 teaspoons salt
2 cups shortening
1 tablespoon vinegar
1 egg, beaten
Water

Sift dry ingredients together. Cut shortening into dry ingredients until mixture is the consistency of coarse meal. Combine vinegar and egg and add enough water to make 1 cup liquid. Add liquid to dry ingredients and mix until dough forms a ball. Divide dough and pat out with hands into desired shape on floured pastry cloth or board or floured sheet of wax paper. Smooth with rolling pin. For baked shell, prick with a fork and bake at 450 degrees F for 12 to 15 minutes.

Keeps several months in freezer tightly wrapped. Yields 5 or 6 (9-inch) crusts.
