Ingredients
1 1/2 cups all-purpose flour
3/4 cup yellow cornmeal, preferably medium-ground
3/4 teaspoon salt
3/4 teaspoon sugar
6 ounces (3/4 cup) cold unsalted butter, cut into small pieces
1/4 cup ice water
Preparation
Pulse flour, cornmeal, salt, and sugar in a food processor to combine. Add butter, and process until mixture resembles coarse meal, about 10 seconds. With the machine running, add ice water in a slow, steady stream until dough just begins to hold together (no longer than 30 seconds).
Shape dough into a disk. Wrap in plastic, and refrigerate until firm, at least 1 hour (or up to 2 days).
