Is it possible to freeze a block of sugarpaste? The smallest pack I can buy is 250g and sometimes I only need a tiny bit but no matter how much I wrap it, it doesn't seem to keep for very long. A girl on my sugar flowers course said she freezes her flower paste and it's fine. I wondered if it was possible to do the same with normal sugarpaste?

Yes, I have heard it is fine. But it will also last for at least six months if you wrap it up nicely so no air can get in, then put it in a ziploc bag and into a cool dark place. You don't need to freeze store bought fondant, as it contains preservatives. Check the best before date on the packet, it will last at LEAST until then.
