Many people ask me about fondant. Fondant was originally used to cover fruitcakes that were shipped from England to the New World and has been used in Europe and Australia for centuries. Fondant recently gained popularity in the U.S. because of its incomparably smooth finish. Fondant is an edible sugar paste made of powdered sugar, gelatin, glucose, glycerin, and water, and is used only as an icing (not a filling). Some people like it, and some don’t. Because fondant firms up, it is easy to handle, and I find that guests who don’t like fondant will simply peel it off. Also, because of the way wedding cakes are cut, guests only get a small amount of fondant with their cake. I prefer not to cover cakes in fondant but I do cover some cakes for aesthetic reasons.
I hope this helps you decide if you want to cover yourcake in fondant or not.
