Pastry Dough

• Cut butter into 1/2-inch cubes.

To blend by hand:

• Blend together flour, butter, shortening, and salt in a bowl with your fingertips or a pastry blender until most of mixture resembles coarse meal, with rest in small (roughly pea-size) lumps. Drizzle 2 tablespoons ice water evenly over and gently stir with a fork until incorporated.

To blend in a food processor:

• Pulse together flour, butter, shortening, and salt in a food processor until most of mixture resembles coarse meal, with rest in small (roughly pea-size) lumps. Add 2 tablespoons ice water and pulse 2 or 3 times, or just until incorporated.

Test mixture:

• Gently squeeze a small handful: It should hold together without crumbling apart. If it doesn't, add more ice water, 1 tablespoon at a time, stirring or pulsing 2 or 3 times after each addition until incorporated (keep testing). (If you overwork mixture or add too much water, pastry will be tough.)

Form dough:

• Turn out onto a work surface and divide into 4 portions. With heel of your hand, smear each portion once in a forward motion to help distribute fat. Gather dough together and form it, rotating it on work surface, into a disk. Chill, wrapped in plastic wrap, until firm, at least 1 hour.
