So... the cake is served at the end of the meal. Most people may not be that hungry anymore and the true is... many guests won't eat their wedding cake. But then why is the wedding cake such an important element of a wedding?
As we do, we turned to our best friend google and our best friend told us that Ancient Roman wedding ceremonies were finalized by breaking a cake of wheat or barley over the bride's head as a symbol of good fortune. The newly married couple then ate a few crumbs in a custom known as confarreatio — the act of eating together.
So... I guess the next wedding cake is going into the bride's face? ;)
