I am making an 8 in block cake this weekend and only need half the block to be cake (I have two more 8 in blocks that are all cake). How do I attach fondant when it's half cake half styrofoam (each side is a different color so it will be the frost one side, attach fondant approach). Would I cover the styrofoam with Press n Seal and then put frosting directly on that? I am nervous it will slide. Thank you for your help!
I've covered cake dummies with fondant with nothing covering them, but if I was mixing that with real cake, and having the fondant touching both, then I would go ahead and cover the cake dummy with press and seal and put a cake plate between the cake and dummy. Styrofoam isn't made for eating.
You can spray a (very very very very) little amount of water on the press and seal, smear it with crisco, or even use something like piping gel or corn syrup to get it to stick.
I attach fondant to styrofoam using crisco.
You could also just run your BC down the styro and then add the fondant.
Your cake layer should be on a board, so it won't come in direct contact with the styro.
