1 1/2 cups all-purpose flour
1 teaspoon salt
1 stick (1/2 cup) cold unsalted butter, cut into bits
3 to 4 tablespoons ice water

In a large bowl whisk together flour and salt and with a pastry blender or your fingertips blend in butter until mixture resembles coarse meal. Add ice water, 1 tablespoon at a time, tossing with a fork to incorporate, until mixture begins to form a dough. On a floured work surface smear dough in 3 or 4 forward motions with heel of hand to slightly develop gluten in flour and make dough easier to work with. Form dough into a ball and flatten to form a disk. Wrap dough in plastic wrap and chill in 1 hour. Dough may be made 1 week ahead and chilled.
