Crostata is the Italian word for crust, pie crust or tart. It can also refer to fruit pastry, fruit tart or jam tart. Nowadays, however, the filling can be anything from fruits (apple , berries, peaches) but also vegetables, like onions, artichokes, as in Crostata di cipolle and Crostata di carciofi, respectively.
Crostata is pronounced "kroh-stah-tah"
