How did the tradition begin to eat...

The wedding cake is thought to have originated with the Egyptians. It started as a cake of wheat or barley and it was broken over the bride’s head to signify fertility. As time progressed, it evolved into the tiered cake like today. It was considered good luck if the bride and groom could kiss while leaning over the cake without knocking it over. It was during the reign of King Edward II of England that the cake was iced white and eaten.
