Tart
A tart is a pastry dish, usually sweet, with an open top not covered with pastry. Sweetened fruit is arranged on pastry, often puff pastry, with or without custard, after which the tart is baked in an oven. The Tarte Tatin is a particular kind of "upside-down" tart, of apples, other fruit, or onions. Some tarts also contain fillings similar to pies, for example pecan pies can be made in smaller sizes. Savoury varieties include German Zwiebelkuchen (Onion tart), or Swiss cheese tart made from Gruyere.
