Use this recipe to make our Roasted Cauliflower and Manchego Hand Pies and our Cherry Tomato, Bocconcini, and Zucchini Pie.
Pulse flour, cheese, sugar, salt, and butter in a food processor until mixture resembles coarse meal. Add egg yolk; pulse to combine. With processor running, drizzle in 1/4 cup water until dough just comes together. (If dough is still crumbly, add up to 1/4 cup more water, 1 tablespoon at a time.) Do not process for more than 20 seconds. Wrap in plastic. Refrigerate until cold, about 30 minutes.
