A pastry is a sweet baked good. If you are into fruit tarts or chocolate eclairs, then you've got a thing for pastries.
Most pastries start out as a soft dough or batter made from flour, sugar, eggs, milk, and butter. A tray of pastry at breakfast could include Danishes and croissants, while dessert pastries might be baklava, cream puffs, and strudel. All of these are variously flavored baked sweets, some formed from thin layers of flaky dough and others filled with fruit, cream, or other fillings. Another type of pastry is pie crust, a buttery dough that forms the base (and sometimes topping) for pies. Pastry originally meant "food made from paste," and paste meant "dough."
