Chocolate eclairs, icons of French patisserie, go back to the 19th century. They are credited to the great pastry chef Marie-Antoine Careme, known as the "king of chefs and chef of kings". Originally these pastries were called "pain a la duchesse" before becoming the eclairs we know today, named for how fast they are eaten — as quick as a flash of lightning. First filled with plain or flavoured pastry cream, chocolate eclairs have grown into an indulgent dessert enjoyed worldwide for the perfect balance between light choux pastry, rich chocolate cream and a glossy glaze.
