A pastry crust is a type of dough used as a base or covering for various baked goods, such as pies and tarts. It is typically made from flour, fat (like butter or shortening), and water, which are combined to create a tender and flaky texture. The dough can be rolled out and shaped to fit a baking dish, providing a delicious foundation for sweet or savory fillings. There are different types of pastry crusts, including shortcrust, puff pastry, and phyllo. Each type has its unique characteristics and uses, with shortcrust being the most common for pies. Proper preparation and baking techniques are essential to achieve the desired texture and flavor in the final dish.
