Step 1

Using a pastry blender or fork, mix flour, shortening, sugar, and salt together until the mixture resembles coarse crumbs.

Step 2

Combine vinegar, egg, and water and mix well. Add wet ingredients to the flour mixture and blend quickly. Be careful not to overwork dough; mix just until liquid is absorbed by the flour mixture. Refrigerate at least 15 minutes before rolling.

Step 3

This dough can be divided into individual crust portions, wrapped, and frozen for later use.
