Choux pastry, or pâte à choux (pronounced [pɑt a ʃu]), is a light pastry dough used to make profiteroles, croquembouches, éclairs, French crullers, beignets, St. Honoré cake, quenelles, Parisian gnocchi, dumplings, gougères, chouquettes, craquelins and churros. It contains only butter, water, flour and eggs. Instead of a raising agent, it employs high moisture content to create steam during cooking to puff the pastry.
