In many households, part of the fun of eating Christmas pudding is finding a trinket that predicts your fortune for the coming year. For instance, finding a coin means you will become wealthy. What will you be if you find a button? A bachelor
A ring means you will get married; while a thimble predicts spinsterhood. The idea of hiding something in the pudding comes from the tradition in the Middle Ages of hiding a bean in a cake that was served on Twelfth Night. Whoever found the bean became "king" for the rest of the night.
