That’s a really great question. Unfortunately, I don’t have an answer. I googled, and all that comes up are the pre manufactured paper sugar sheets. Which, apparently can be frozen on a cake. Homemade ones are combo of corn syrup/glucose and coloured sugar. I would think the glucose would keep the sugar supple and preventing disintegration once thawed. But that’s an educated guess.
