Ok, let me tell you what happened to me today on this topic!
My first full fondant'd-styrofoam cake (for an upcoming bridal show). I pulled all the advice I've stored up about fondant and rather than screw around with icing styro's, I went with the "mist the styro" plan.
Ok, what you guys didn't tell me was that "misting" the styro means to "MIST" the styro ... and the big commerical sprayer on my sink is NOT the same as "misting" the styro!!
oh. my. gosh. I tried putting this fondant on the styro and it got excessively wet and turned to goo! It was sticking to everything except my styro!
Oh....did I tell you it was black fondant? You should have seen my hands!
It if wasn't so funny it would have been horrible!
I felt like the person in the sit-com who put too much soap in the washer and too much rice on the stove! It was hysterical!
For the other tiers, I wet the styro, then used a paper towel to get the excess water off, THEN applied the fondant and it worked MUCH better!
So tucan, when these guys tell you to "mist" it, they really do mean to just "mist" it!
