Blend flour and salt in a large bowl. Cut shortening into flour mixture with pastry cutter or fork until coarse crumbs form. Stir in enough water with a fork just until the dough holds together.
Divide the dough in half. Shape into two 1/2-inch thick disks. Wrap in plastic wrap. Chill for 30 minutes.
Roll out each disk 2 inches larger than the pie plate on a lightly floured surface. Line a pie plate with 1 unbaked pie crust. Fill crust according to recipe directions. Top with the remaining unbaked pie crust. Bake according to recipe directions.
