Combine flour, salt and butter in a food processer, or use a pastry blender. Process until crumbly texture. Add ice water one tablespoon at a time, mixing just until combined. Place dough into a large mixing bowl, divide in half. With hands, press each half together to form a ball. Wrap each ball of dough in plastic wrap and refrigerate 15-20 minutes. Once chilled, roll to form. Roll 1" larger than pie pan.
