Did someone say cake? Where there’s a cake, there is bound to be a party, right? So, what is a King’s Cake and why do we eat it? Sometime between January 6th, King’s Day or the Twelfth Night of Christmas, and Lent (a time of abstinence, penance and self-control) we have the most outrageous party of all, Mardi Gras. And what is a party without a luscious cake? But this isn’t just any old cake. The King’s Cake is rich in tradition and folklore.
