Hi everyone. This is my first experience with melted sugar. We melted and dyed some isomalt blue and poured it into a prepared cake board to create the water for a moat around a castle cake. Looks great but we poured it about a day ago, maybe two and it's getting a film on top of it. Looks whiteish. We're going to hit it with a flame before the party but can anyone tell me what this is and how to avoid it?
My guess is that it's the result of condensation.
Has it been very rainy or humid where you are? Has the isomalt been very cool, then warmed and cooled again?
Isomalt isn't affected as quickly, or badly, by water as real sugar, but it can still get sticky and get white-is.
