These little fèves (or beans) are collectible porcelain charms or figurines, usually in the shape of French icons. The amazing fèves shown above are beloved French CHOCOLATE items like truffles, hot cocoa, and of course the revered cacao pod.
During the Epiphany families share King Cake or "galette des rois" that are laced with a single fève surprise. The person who finds the much sought after fève in their slice of cake is considered the king for the day and gets to wear the paper crown which is usually shaped around or sometime attached below the cake. In France some bakeries even offer customized fèves depicting common cultural themes from movie stars to cartoon characters.
