What is croissant?
Croissant is a buttery, flaky, French viennoiserie pastry inspired by
the shape of the Austrian kipferl but using the French yeast-leavened
laminated dough.
Croissants are named for their historical crescent shape, 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.
