pastry dough for 9-inch single crust pie

Pie dough, or pâte brisée, is a foundational pastry prepared from a simple combination of flour, fat (typically butter or shortening), salt, and cold water. The dough originates from European baking traditions and has become fundamental to both sweet and savory pie-making across global cuisines. The key to successful pie dough lies in the ratio of fat to flour—typically around 1:2 or 1:3—and in keeping all ingredients cold to prevent the fat from melting into the flour before baking, which would result in a tough, dense crust rather than the desired flaky, layered texture. When properly prepared, the fat creates small pockets that steam during baking, producing the characteristic tender, crispy crust. Single-crust doughs for 9-inch pies typically contain approximately 1.5 to 2 cups flour, 6-8 tablespoons cold butter (or other fat), a pinch of salt, and 4-6 tablespoons ice water.

Pie dough serves as the structural foundation for both sweet and savory pies, tarts, and galettes. In American baking, it is essential for fruit pies (apple, cherry, peach), cream pies, custard pies, and savory preparations such as pot pies and quiches. Single-crust versions are used when filling alone provides sufficient structure or when a blind-baked crust is preferred. The dough may be rolled thin (approximately 1/8 inch) and fitted into a pie tin, with edges crimped for both functional and decorative purposes. Proper chilling before and after shaping prevents shrinkage during baking. The crust is typically baked at 400-425°F until golden brown, though blind-baking (pre-baking with weights) may be necessary for cream or custard fillings to prevent a soggy base.
