A quiche crust, also known as a pie crust, is a pastry dough used as the base and sides of a quiche, a savory French tart filled with eggs, cream, cheese, and various other ingredients. Quiche crusts are typically made with a combination of flour, butter, salt, and water, and can be either shortcrust or puff pastry.
The importance of a good quiche crust lies in its ability to provide a sturdy and flavorful base for the quiche filling. A well-made crust will be flaky and tender, yet strong enough to hold the filling without becoming soggy. Additionally, the crust can be used to add flavor and texture to the quiche, with different types of flour, butter, and seasonings creating different taste and texture profiles.
