My brother-in-law insisted upon having the top tier of his wedding cake made into a hamburger. My sister-in-law and I designed the bottom three tiers, so as to have a “rutic yet elegant” wedding cake that fit right in with her whole wedding theme. Especially since they were serving gourmet hamburgers as the main course! The hamburger is all cake, and the fries and trimmings (and the plate as well) are all made of gumpaste or fondant.
