Roscon de reyes is a traditional dessert, served the night before or the morning of reyes or epiphany on jan. 6. Dia de reyes or simply reyes is the day when children in spain receive gifts from the reyes magoswise men or magithe three kings who brought baby jesus gifts. Instead of gifts from santa claus, the children receive them from the reyes magos. It is traditional to put several surprises inside the roscon. A porcelain figure of a baby wrapped in foil and a dry bean are hidden in the dough. Whoever finds the baby will have good luck and be the king of the party, but if you find the bean, you pay for the cake.
