Pie

This article is about the baked goods. For the mathematical constant, see Pi. For other uses, see ."Raspberry pie" redirects here. It is not to be confused with Raspberry Pi. A pie is a baked dish which is usually made of a pastry dough casing that covers or completely contains a filling of various sweet or savouryingredients.

Pies are defined by their crusts. A filled pie (also single-crust or bottom-crust), has pastry lining the baking dish, and the filling is placed on top of the pastry but left open. A top-crust pie, which may also be called a cobbler, has the filling in the bottom of the dish and covered with a pastry or other covering before baking. A two-crust pie has the filling completely enclosed in the pastry shell. Flaky pastry is a typical kind of pastry used for pie crusts, but many things can be used, including baking powder biscuits, mashed potatoes, and crumbs.

Pies can be a variety of sizes, ranging from bite-size to ones designed for multiple servings.
