The wedding cake has been a part of the ceremony since the ancient Greeks and Romans. As part of the nuptials, the groom broke bread over the bride’s head. This was to symbolize her submission, the end of her purity, and to represent good luck and fertility. During the Middle Ages, a new take on wedding cake began. The newer approach included cakes that were high-stacked and the newlyweds would kiss over it. If they were successful in kissing without knocking the cake over, then it was believed that they would be blessed with many children. Taking the goal of the bride’s fertility a step further, the English decided that child-bearing would be best increased by throwing the cake at the bride.
