Croissant is a buttery, flaky, viennoiserie pastry inspired by the shape of the Austrian kipferl but using the French yeast-leavened laminated dough. Croissants are a common part of a continental breakfast in many European countries. Uncooked croissant dough can also be wrapped around any praline, almond paste, or chocolate before it is baked, or sliced to include sweet or savoury fillings. It may be flavored with dried fruit such as sultanas or raisins, or other fruits such as apples. In France and Spain, croissants are generally sold without filling and eaten without added butter, but sometimes with almond filling.
