Nectarine, Plum, and Raspberry Pie

Blend together flour, butter, shortening, and salt in a bowl with your fingertips (or pulse in a food processor) until mixture resembles coarse meal with some roughly pea-size butter lumps. Drizzle evenly with 5 tablespoons ice water and gently stir with a fork (or pulse) 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 combined. (Do not overwork mixture, or pastry will be tough.) Turn out dough onto a work surface and divide into 6 portions. With the heel of your hand, smear each portion once or twice in a forward motion to help distribute fat. Gather all of dough together with scraper and press into 2 balls, then flatten each into a 5" disk. Chill dough, each disk wrapped tightly in plastic wrap, until firm, at least 1 hour.
