A canelé is a small French pastry with a center of soft, tender custard and a dark, thick caramelized crust. This unique dessert is a specialty of the Bordeaux region of France but can often be found in Parisian patisseries as well. Made with fresh eggs, butter, milk, and flour and flavored with rum and vanilla, the custard batter is traditionally baked in a copper mold, giving the canelé its signature shape and caramelized crust.
