This recipe provides instructions for making a perfect pie crust for a 9-inch or 10-inch double crust pie. It calls for mixing 2 1/2 cups of flour, 1 teaspoon of salt, and 2 tablespoons of sugar. Then working 12 tablespoons of cold unsalted butter and 8 tablespoons of Crisco into the dry ingredients until pea-sized. Approximately 5 tablespoons of ice water is added slowly until the dough just holds together. The dough is then wrapped, chilled for 30 minutes, and rolled out with extra flour before using.
