Mix the base: In a food processor (or bowl with a pastry cutter), combine 2 ½ cups flour, ½ cup cold butter, ½ cup shortening, and ⅛ teaspoon salt. Pulse until crumbly, small pieces of fat should remain visible.
Add water: Drizzle in ice water 1 tablespoon at a time, pausing briefly between additions, until the dough comes together.
Form the dough: Turn onto a floured surface. Gently press the dough together until it forms a flat disk. Divide into two equal portions for a double crust or keep as one for a single crust.
Chill: Wrap in plastic wrap and refrigerate at least 2 hours (or overnight).
Roll it out: On a floured surface, roll the dough into a 9-12 inch circle. Roll it several inches larger than your specific pie plate before transferring to your pie plate, trim, and crimp edges.
Chill again: Refrigerate the shaped crust for 30 minutes before baking to prevent shrinking.
Bake or fill: Add your pie filling and bake as directed. For blind baking, line with parchment and pie weights, bake at 375°F for 10–15 minutes, then continue until golden.
