Using nothing more than a muffin tin, Chef John creates one of the world’s most unique treats. For these classic French baked custard cakes, make a simple paste of flour, sugar, egg yolks, salt, vanilla and wine. Simmer butter and milk and whisk into the paste to create a smooth and thin batter. Melt butter together with beeswax and brush into your molds. Ladle in batter and bake until well browned and beautiful! Get the recipe for Canelés de Bordeaux.
