1 stick cold unsalted butter, cut into small pieces
1/4 cup cold water
How to Make It
Toss together flour and salt in a large bowl. Add butter pieces and blend into flour with fingertips until mixture resembles cornmeal. Add water and stir with a fork until dough just comes together into a ball. Knead briefly until barely smooth, then pat dough into a 1-inch-thick disk, wrap in plastic wrap and chill for 15 minutes.
On a lightly floured surface, roll out dough into a 12-inch circle. Roll dough onto rolling pin and unroll into a pie pan. Prick all over with a fork. Line the pastry shell with a 15-inch sheet of aluminum foil, letting edge hang over top. Freeze for 15 minutes.
Preheat oven to 375°. Fill the foillined shell with 2 cups dried beans. Bake for 20 minutes, remove foil and beans and bake 17 minutes more. Remove from oven and cool on a rack before filling.
