A turnover is a kind of pastry made by placing a filling on a piece of dough, folding the dough over, and sealing it. Turnovers can be sweet or savory and are often made as a sort of portable meal or dessert, similar to a sandwich.
It is common for sweet turnovers to have a fruit filling and be made with a shortcrust pastry or puff pastry dough; savory turnovers generally contain meat and/or vegetables and can be made with any sort of dough, though a kneaded yeast dough seems to be the most common in Western cuisines. They are usually baked, but may be fried.
Savory turnovers are often sold as convenience foods in supermarkets. Savory turnovers with meat or poultry and identified as a turnover (for example, "Beef Turnover" or "Cheesy Chicken Turnover") have to meet a standard of identity or composition, and must contain a certain amount of meat or poultry.
"Turnover" should not be confused with the sports term of the same name.
