With minimal ingredients and fuss, you can make your own crust in less time than it takes to go buy one. Prep: 10 minutes.
Combine flour and salt in a large mixing bowl, and cut in butter with a pastry blender (or pulse in a food processor) until dough resembles coarse meal. Add 3 tablespoons ice water, and stir, adding 2 to 4 more tablespoons water until dough forms a ball and leaves side of bowl.
Form into 2 flat, round discs (or balls), cover with plastic wrap, and chill until ready to use.
