In France we celebrate the Kings, not the Kings of France but the three kings who were there when Jesus was born "Les Rois Mages". Here is the special cake we eat starting January first. It is a butter pastry with an almond filling, and there is a surprise inside it is called a fève (used to be a dried bean) and whoever gets it is the King. Usually the youngest person goes under the table and the cake is cut and the youngest tells who will have each part.
Usually when I cut in it, I always hit the surprise (fève)
