Tart

A tart is a baked dish consisting of a filling over a pastry base with an open top not covered with pastry. The pastry is usually shortcrust pastry; the filling may be sweet or savoury, though modern tarts are usually fruit-based, sometimes with custard. Tartlet refers to a miniature tart.

The categories of 'tart', 'flan', and 'pie' overlap, with no sharp distinctions, though 'pie' is the more common term in the United States.

Early medieval tarts generally had meat fillings, but later ones were often based on fruit and custard.

Tarte Tatin is an upside-down tart, of apples, other fruit, or onions.

Savoury tarts include quiche, a family of savoury tarts with a mostly custard filling; German Zwiebelkuchen 'onion tart', and Swiss cheese tart made from Gruyere.
