A symbol of good luck and fertility, cake has been a part of wedding celebrations since Roman times, when a small bun was broken above the bride's head at the close of the ceremony. Wheat, the main ingredient, symbolized fertility: crumbs were eagerly sought by guests as good-luck charms.
During the Middle Ages, custom required the bride and groom to kiss over a pile of small cakes donated by wedding guests. In Elizabethan times, bridesmaids baked small, sweet buns with currants, which served as the centerpiece for the wedding feast. In the 17th century, it was an innovative visiting French baker who frosted the stack of buns so that they would stand upright--creating the first tiered and frosted wedding cake! The Chinese originated the custom of serving each guest a slice of cake to spread the good luck.
