I had my second attempt and making a cake and decorating it with Fondant.However, this time I made my fondant from scratch.Results = TOTALLY WORTH IT!!!The store bought fondant had a strange taste to it and but the homemade marshmallow fondant tasted just like marshmallows. It was a little difficult to make and you will probably work up a sweat kneading and flattening the fondant but that just means you won't feel bad eating the 2nd piece of cake.
This blog has a great Make-a-Cake series that gave very good detailed instructions.I think the results were pretty good. What do you think?
