I don’t have my MC recipe in front of me, but it’s WAY different than yours. Mine is chocolate, corn syrup, and just a little glucose. You may live in an area that doesn’t have corn syrup. Have you used this same recipe before? If so, did you have problems with it then also?
Sugarqueen, if it was just “sweat” it should eventually dry out, not get worse, right? It sounds like it’s the glucose leeching out to me, but I’m not sure.
