Add 3 tablespoons ice water, toss until mixed and press dough onto bottom and up the side of a 9-inch deep-dish pie plate. Crimp edge; prick with fork and chill 30 minutes. (Crust can be made 2 weeks in advance, wrapped, and frozen.)

Use the dough as you would any other dough with the filling you choose to enjoy. Happy Pie-ing!
