Ingredients
1 1/4 cups all-purpose flour
4 1/2 teaspoons granulated sugar
1/4 teaspoon salt
1 stick cold unsalted butter, cut into small pieces
1 large egg yolk
2 tablespoons ice water
Preparation
Pulse flour, sugar, and salt in a food processor until combined. Add butter, and process until mixture resembles coarse meal, about 10 seconds.
Lightly beat yolk with ice water. With processor running, add yolk mixture in a slow, steady stream through the feed tube, and process until dough just holds together (no longer than 30 seconds).
Turn out onto a work surface, and shape into a disk. Wrap in plastic, and refrigerate for at least 1 hour (or up to 2 days).
