In a bowl, whisk together the 1 1/2 cups unbleached all-purpose flour, 1/4 cup granulated or packed light brown sugar, and 1/2 teaspoon fine sea salt. Slowly drizzle in 8 tablespoons (113 g) unsalted butter and stir with a fork, just until the mixture looks moist and crumbly. ☞ TESTER TIP: If the dough is dry, add the remaining butter, 1 tablespoon (14 g) at a time.
