My fiance is from the South and his family weddings ALWAYS include a grooms cake, which is served at the reception at the same time as the wedding cake. My question (which has stumped his family) is how many should the grooms cake serve? Does every guest get a slice (which means I am ordering double the cake I thought I was)? Do guests get an either/or choice? Does every guest get a slice of wedding cake and then the grooms cake is extra for some percentage of our guests who want it?This is making me crazy.
