Wedding cake are an art and usually served at wedding following the  dinner. 
I love wedding cake. It is so beautiful and it is nice to see the bride and groom feed each other at weddings.
Wedding cake were created to bring good luck to all guests at the wedding and the newly weds. 
It is a great tradition. My favorite cakes are the huge, multilayered ones with figurines on top.
Some wedding cakes are not edible and the groom only share an edible on between themselves. 
Interesting, I did not know that! Every wedding I have been to has had an edible cake. I wonder why only the grooms get to eat the cake at some weddings!
It probably has to do with cost, but the cost between a non edible and edible are minimal so it also baffles my mind. 
I am sure there is a cultural reason for it. Wedding customs are so diverse. It is great to see all the ways people celebrate a union!
That's true, each culture has different procedure like some cultures send the groom's elders to request a union between the two parties.
Fascinating. These traditions have been practiced for quite a long time. I wonder what the earliest weddings looked like!
