A croissant is a French pastry made from puff pastry in a crescent shape.

Pastry is baked food made with a dough of flour, water, and shortening that may be savoury or sweetened. Sweetened pastries are often described as bakers' confectionery. The word "pastries" suggests many kinds of baked products made from ingredients such as flour, sugar, milk, butter, shortening, baking powder, and eggs. Small tarts and other sweet baked products are called pastries as a synecdoche. Common pastry dishes include pies, tarts, quiches, croissants, and pasties.
