Choux pastry  —  pâte à choux, a.k.a. choux paste and cream-puff pastry  —  is made by cooking milk or water, butter and flour in a saucepan. After the mixture has cooled, some eggs are beaten in and the paste is piped into different shapes, like a large ring or small mounds, and baked in oven until puffed in hollow domes.

When cold, these chou buns  —  cream puffs  —  are filled with various sweet or savoury fillings and served as cocktail snacks, as a dessert, etc. For example éclairs and profiteroles are made of choux pastry.
