In Roman times, a slave would be designated as "king for a day" and have authority. The origins of the Epiphany cake or "La Galette des Rois" date back to the Middle Ages and is associated with the biblical Magi who brought gifts for baby Jesus. The traditional recipe includes puff pastry, almonds, sugar, eggs, butter and a hidden fava bean. By tradition the cake is eaten on January 6th to commemorate the visit of the Three Kings, but now it is consumed from late December through January paired with champagne. Eighty percent of Epiphany cakes are sold in Paris.
