In food processor, add first three Pie Crust ingredients. Cover; pulse to combine (or use bowl and pastry blender). Add 1 cup cold butter; pulse to coarse crumbles. With food processor on, gradually add ice water a few tablespoons at a time, just until dough comes together when pressed. Gather dough together and press to form a wide, flat circle. Wrap in plastic wrap; refrigerate at least 30 minutes.
