Puff pastry, also known as pâte feuilletée, is a flaky light pastry made from a laminated dough composed of dough and butter or other solid fat. The butter is put inside the dough, making a paton that is repeatedly folded and rolled out before baking.

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.
