Tart Shell

Preparation

1. Step 1

   Blend together flour, sugar, salt, butter, and shortening with your fingertips or a pastry blender (or pulse in a food processor) just until most of mixture resembles coarse meal with small (roughly pea-size) butter lumps. Drizzle evenly with 3 tablespoons ice water and gently stir with a fork (or pulse in food processor) until incorporated.

   Step 2

   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. (If you overwork mixture, pastry will be tough.)

   Step 3

   Turn out mixture onto a lightly floured surface and divide into 6 portions. With heel of your hand, smear each portion once or twice in a forward motion. Gather dough together with scraper and press into a ball, then flatten into a 6-inch disk. Chill, wrapped in plastic wrap, until firm, at least 1 hour.

   Step 4

   Roll out dough with a floured rolling pin into a 13-inch round on a lightly floured surface and fit into tart pan. Trim excess dough, leaving a 1/2-inch overhang, then fold overhang inward and press against side of pan to reinforce edge. Lightly prick bottom and sides with a fork. Chill 30 minutes.

   Step 5

   Preheat oven to 375°F.

   Step 6

   Line tart shell with foil or parchment paper and fill with pie weights. Bake in middle of oven until pastry is pale golden along rim, 20 minutes. Carefully remove foil and weights and bake until pale golden all over, 10 minutes more. Cool in pan on a rack.
