Blend together flour, butter, shortening, and salt in a bowl with your fingertips or a pastry blender (or pulse in a food processor) until most of the mixture resembles coarse meal with some small (roughly pea-size) butter lumps. Drizzle evenly with 2 tablespoons ice water and gently stir with a fork (or pulse in processor) until incorporated.
Squeeze a small handful: If it doesn't hold together, add more ice water, 1 tablespoon at a time, stirring (or pulsing) until just incorporated, then test again. (Do not overwork, or pastry will be tough.)
Turn out mixture onto a lightly floured surface and divide into 4 portions. With heel of your hand, smear each portion once or twice in a forward motion to help distribute fat. Gather dough together with scraper and press into a ball, then flatten into a 5-inch disk. Chill dough, wrapped tightly in plastic wrap, until firm, at least 1 hour.
