Éclair: French filled choux pastry

Composition and preparation

The basic components are choux dough piped into an elongated shape, oven-baked to form a light shell, then cooled. The shell is filled either by slicing the pastry open or by piping filling through a small hole. A smooth icing or ganache is spread on top to seal and decorate. Variations in dough hydration, oven temperature and piping size yield different textures and sizes.

History and name

The éclair developed from French choux-pastry traditions that became central to European patisserie. The word éclair is French for "lightning," a name that is commonly explained by the idea that the pastry is eaten quickly. The form and common fillings familiar today were established within 19th-century French baking practice and later spread internationally.

Varieties and examples

Classic eclairs are chocolate-topped with vanilla or chocolate pastry cream, but modern pastry chefs offer many flavors and presentations. Common variations include:

• Vanilla crème pâtissière or custard
• Chocolate or coffee flavored cream
• Fruit-flavored fillings such as raspberry or lemon
• Caramel or salted-caramel toppings
• Savory versions filled with cheese or herbed mousses (less common)

Serving, storage and distinctions

Éclairs are typically sold in patisseries and cafés and are best eaten fresh; pastry shells can soften when refrigerated, so many bakers fill them shortly before sale. They are distinct from round choux confections such as cream puffs (profiteroles) by their elongated shape and often by the use of a flat glaze rather than dusting or sauce. As a staple of classic French pastry, the éclair remains a vehicle for both traditional tastes and contemporary culinary experimentation.
