Cornmeal makes this dough slightly tricky to work with. To prevent cracks, bang the center of the disk with a rolling pin to soften before rolling.
- 2 cups all-purpose flour
- 1/2 cup finely ground cornmeal
- 3 tablespoons sugar
- Coarse salt
- 2 sticks unsalted butter, cut into small pieces
- 1 large egg yolk
- 1/4 to 1/2 cup ice water
Pulse flour, cornmeal, sugar, and 1 3/4 teaspoons salt in a food processor until combined. Add butter; pulse until mixture resembles coarse crumbs with no large pieces remaining. Add yolk, and drizzle 1/4 cup water evenly over mixture. Pulse until mixture just begins to hold together when pressed between 2 fingers (it should not be wet or sticky). If dough is too dry, pulse in more water, 1 tablespoon at a time.
Turn out dough onto work surface, and knead once or twice to combine. Divide dough in half. Shape into disks. Wrap in plastic wrap, and refrigerate for at least 30 minutes.
