Use this recipe to make our Easy Citrus Tart.
In a food processor, pulse flour and sugar to combine. Add butter; pulse until mixture resembles coarse meal, about 15 seconds. In a bowl, lightly beat yolk with ice water. With machine running, add egg mixture in a slow, steady stream; process until dough just holds together. On a piece of plastic wrap, press into a flattened disk; wrap well. Chill at least 1 hour.
