You can also buy Isomalt sticks (in colors) just melt them down and use them any way you want. You can ckeck it out at: cakeplay.com. You can also do the same effect with chocolate melts/candy coating and the ice (it's just not transparent like the isomalt).
Isomalt crystals and isomalt sticks stand up better in the humidity. I made an pulled sugar recipe and the items broke down in the TN humidity. The Isomalt hold up much better so you can make things a few days in advance. You just shouldn't eat a lot of it, you will be running to the bathroom if you eat it in large quantities. lol
I've tried that recipe... VERY sticky - but it works. Don't burn yourself.. sugar burns are the worst.
