Directions

1. In the bowl of a food processor, combine flour and salt; pulse to combine. Add butter, and pulse until mixture resembles coarse crumbs with some larger pieces remaining, about 10 seconds. (To mix by hand, combine dry ingredients in a large mixing bowl, then cut in butter with a pastry blender.)
2. With machine running, add ice water through feed tube in a slow, steady stream, just until dough holds together without being wet or sticky. Do not process more than 30 seconds. Test by squeezing a small amount of dough together; if it is still too crumbly, add a bit more water, 1 tablespoon at a time.
3. Turn out dough onto a clean work surface. Divide in half, and place each half on a piece of plastic wrap. Shape into flattened disks. Wrap in plastic, and refrigerate at least 1 hour or overnight. The dough can be frozen for up to 1 month; thaw overnight in the refrigerator before using.
