What is the symbolic of cutting of the wedding cake during ceremony?

Wedding cakes take center stage in the traditional cake cutting ceremony, symbolically the first task that bride and groom perform jointly as husband and wife. This is one tradition that most of us have witnessed many times. The first piece of cake is cut by the bride with the "help" of the groom. This task originally was delegated exclusively to the bride. It was she who cut the cake for sharing with her guests. Distributing pieces of cake to one's guests is a tradition that also dates back to the Roman Empire and continues today. Following the tradition of breaking the bread over the bride's head, guests would scramble for crumbs that fell to the ground. Presumably the consumption of such pieces ensured fertility. But, as numbers of wedding party guests grew, so did the size of the wedding cake, making the distribution process impossible for the bride to undertake on her own. Cake cutting became more difficult with early multi-tiered cakes, because the icing had to be hard enough to support the cake's own weight. This, of necessity, made cutting the cake a joint project. After the cake cutting ceremony, the couple proceed to feed one other from the first slice. This provides another lovely piece of symbolism, the mutual commitment of bride and groom to provide for one another..
