Cna anyone tell me what to do with sticky sugar tiles? I made them last night with isomalt and left them in my sugar tile mold overnight and this morning they were sticky on top. I turned on the AC hoping it would get rid of the humidity, but it's not helping. Did I do something wrong? Any way I can get them "unsticky"? Also, when I make them in advance, any suggestions for storing them? TIA, Melissa
