• 8 oz. (1 cup) cold unsalted butter
• 9 oz. (2 cups) all-purpose unbleached flour
• 1/4 cup sugar
• 1/4 tsp. salt
• 1/4 cup cold water

1. Cut the butter into 1/2-inch cubes.
2. Dump the flour, sugar, and salt into the bowl of a stand mixer fitted with the paddle attachment (or in a large bowl, if mixing the dough by hand).
3. Mix for a second or two to blend the dry ingredients.
4. Add the butter and then, running the mixer on low (or by hand with two knives or a pastry cutter), work the mixture until it's crumbly and the largest pieces of butter are no bigger than a pea (about 1/4 inch).
5. The butter should remain cold and firm.
6. To test it, pick up some butter and pinch it between the thumbs and forefingers of both hands to form a little cube.
7. If the butter holds together as a cube and your fingers are not greasy, then the butter is still cold enough.
8. If your fingers look greasy, put the bowl in the refrigerator for 15 min. to firm up the butter before adding the water.
9. As the mixer turns on low (or tossing with a fork if mixing by hand), sprinkle the cold water evenly over the flour and butter.
10. Work the dough until it just pulls together as a shaggy mass.
11. To roll out the dough for a double-crust pie -- Cut the dough in half and pat each piece into a thick flattened ball (see Shape and roll the dough).
12. Lightly flour your work surface and tap one of the dough balls down with four or five taps of the rolling pan.
13. Begin rolling from the center of your dough outward.
14. Stop the pressure 1/4 inch from the edge of the dough.
15. Lift the dough and turn by a quarter and repeat the rolling until the dough is at least 12 inches in diameter.
16. Be sure to re-flour the work surface if your dough is sticking.
17. Using a pot lid or a circle of cardboard as a template, trim the dough to form a 12-inch round (this should give you a 11/2-inch margin all around your 9-inch pie pan).
18. Fold the dough in half, slide the outspread fingers of both hands under the dough, and gently lift it and transfer it to the pie pan.
19. Unfold and ease the dough round into the bottom of the pie pan without stretching it.
20. Roll out the other dough ball and cut a second 12-inch round to be used as the top crust.

Yields two 12-inch rounds, enough for one 9-inch double-crust pie.
