Every year starting on January 6th, la galette de rois (the cake of the three kings), a cake made of frangipane (almond cream paste) and a buttery crust, is sold in patisseries all over France. These delicious cakes celebrate the Feast of the Epiphany, where the three wise men came to see the baby Jesus. In certain parts of France the cake is made with brioche and filled with glazed fruit.
A feve- a little china figure is hidden inside of the cake, and whoever gets it, (without breaking a cap when biting into it) is crowned king and gets to choose his queen. The cake is usually sold with a gold paper crown (I suspect if Hermes or Vuitton sells the cake, a real crown is provided).
This year the version from Poilane boulangerie has a crown made of oak leaves and the feve is a white cermaic handmade acorn by Le Petit Atelier de Paris.
