I made a skateboard cake last night and originally planned to make it two layers. After thawing, cutting and assembling the pieces to get the shape I wanted, I decided it would look better with just one layer. So I have a 6" round and half of a 12" square left over. I rewrapped it and put it back in the freezer. Is this ok, or will re-freezing it do something undesirable to it? By the way, I didn't handle the extra 6" round or the other half of the 12" square, other than just cutting the 12" in half.
I have been researching this lately too. The general consensus is that it is not desirable, though I'm not sure why. The only positive responses I really got were along the lines of 'why not try it and see'. Sorry I don't know more, just that people keep telling me 'no'.
If it is not for sale, try it. For resale where I live, you can't refreeze.
