Choux pastry

A cooked dough of water or milk, butter, flour and eggs that puffs into hollow, crisp shells in the oven.

Choux pastry: golden, hollow choux pastry puffs and piped eclairs on a baking sheet, one puff cut open to show the hollow interior
  • Doughs, batters and pastry foundations
  • French

Also called: pâte à choux

Liquid and butter are brought to a boil, the flour is stirred in all at once and cooked briefly into a smooth paste, then eggs are beaten in one at a time until the dough is glossy and falls from the spoon in a thick ribbon. Piped and baked in a hot oven, the water in the dough turns to steam and puffs each piece, leaving a hollow inside that sets as it dries.

Choux makes éclairs, cream puffs, profiteroles and Paris-Brest, and savory gougères. Opening the oven too early can make the shells collapse.
