An éclair is a type of pastry made from choux dough, which is light and airy. It is typically filled with cream, such as pastry cream or whipped cream, and is often topped with a layer of chocolate icing. The dough is piped into long, thin shapes and baked until golden brown, creating a hollow center perfect for filling. Éclairs are popular in many countries and are often enjoyed as a dessert or sweet treat. They can be found in various flavors, including vanilla, chocolate, and coffee. This pastry is a classic in French cuisine and is commonly served in patisseries and bakeries around the world.
