January is rather king-heavy in its celebrations. At the beginning of the month, we've got the baby Jesus, who some call the King of Kings; right after that comes the birthday of Elvis, the King of rock and roll; and, finally, there is Martin Luther King, jr. Holiday. Three kings. Count 'em. It was all too perfect to pass up. Rather than make a straightforward, Jesus-oriented King's cake cake, I could celebrate all three kings by adding three different kinds of beans.
