Choux Pastry

Choux pastry (French: pâte à choux) is a light pastry dough made by cooking liquid, fat and flour together, then incorporating eggs. During baking, water in the dough turns to steam and expands the structure, creating a hollow or partly hollow shell that can be filled with sweet or savoury preparations.

How choux pastry is made

1. Bring water or a water-and-milk mixture, butter and salt to a boil.
2. Add the flour all at once and stir vigorously until it forms a cohesive paste called a panade.
3. Return the panade to moderate heat and stir to dry it slightly; a thin film may form on the bottom of the pan.
4. Transfer to a mixing bowl and allow it to cool briefly so the eggs do not cook on contact.
5. Add beaten eggs gradually, mixing until the paste is smooth, glossy and pipeable.
6. Pipe the required shapes and bake until expanded, set and evenly coloured.

What determines the texture?

The amount of egg must be adjusted to the flour, drying time and dough consistency. The finished paste should hold its piped shape but remain soft enough to expand. Too much egg can make it runny; too little can produce dense shells with poor expansion. Oven heat and adequate baking time are essential to set the structure and dry the interior.

Common choux pastry products

• Éclairs: elongated shells filled with pastry cream and glazed.
• Profiteroles and cream puffs: round shells filled with cream or ice cream.
• Paris-Brest: a ring-shaped choux pastry traditionally filled with praline cream.
• Gougères: savoury choux pastries enriched with cheese.
• Croquembouche: a tower of filled choux buns bound with caramel.

Chef’s tip: Add eggs gradually and check the consistency before adding the final portion. Bake until the shells are well coloured and dry enough to hold their shape; opening the oven too early can cause collapse.

Key distinction: Choux pastry is cooked on the stovetop before eggs are added, then expanded mainly by steam in the oven. It is not a laminated dough or a conventional creamed cake batter.
