Hey I came across a cupcake filled with candyfloss today they looked amazing!

I wondered has anyone tried this and how do they actually turn out? I would assume that the candyfloss would crystallise would it not?

I might have to give these a go!! :D

Perhaps a photo?  I have used cotton candy (I am assuming that's what you are taking about) for decorating before on the unicorn cake in my portfolio.  I think it held up for about two hours.  Then it started to disintegrate.
