I remember answering that one :
//// 12th Night Cake | King & Queen Cake
The celebration of Twelfth Night, the traditional last day of Christmas, is a custom that has largely died out now, but at one time there was a bigger party on Twelfth Night, which is the night of the 5th of January, than on Christmas itself. 12th night is traditionally (and merrily) marked by a feast of food and drink (like Lambswool)- and it is also marked by the baking of two special cakes, the King and Queen cake.////
