Add a portion of the flour (1 ½ cup), plus the salt and butter to a food processor, or large bowl.
Combine the flour and butter until a paste forms, and then add the rest of the flour. Continue combining the mixture until it has the consistency of breadcrumbs.
Add 4 tablespoons of water to the mixture, and fold it into the mixture using a small spatula. If the dough is still falling apart add an additional 2 tablespoons of butter
Form a ball with the dough, and slice in half. Wrap each half in plastic wrap and place in your refrigerator for at least one hour.
After the dough has chilled, remove it from the refrigerator and roll each dough ball out into a 12-inch circle.
Roll one of the pie crusts back onto your rolling pin, and then gently place the crust into a 9" pie pan. Gently press the crust into the bottom of the pan.
