Definition
A croissant is a buttery, flaky, viennoiserie pastry of Austrian origin, named for
its historical crescent shape.
Croissants and other viennoiserie are made of a layered yeast-leavened dough.
The dough is layered with butter, rolled and folded several times in succession, then rolled into a
thin sheet, in a technique called laminating.
The process results in a layered, flaky texture, similar to a puff pastry.
