Using this new form of fondant artistry should be used on a heavy cake consistency. It can, however, be used on the traditional cake mix purchased in a store. Fondant is heavier than traditional knife spread frosting. Pre-made fondant that is available in the cake decorating section in stores has little flavoring. A homemade fondant can be made quickly for very little cost, and tends to have a better flavor than the pre-made store bought version
