Buddy just poured isomalt over ice in a bucket. I'm not sure how long he let it set, but he took it out and loosened the ice around it, though some of it I'm sure he had to let melt, and it came out in a really neat coral shape.
MissRobin - I bet that was great! Did you use white chocolate? That would make great coral! And you could dust it to make it more authentic too! I may have to use that idea
