I've been making these for quite awhile and have had no problems. However, the last 4 or 5 batches I've made, there is moisture sitting on top of the melts. There's like little drops of liquid on top of each melt. They aren't in the freezer more than 20 minutes, I've tried cutting back on the FO, I've used tried and true FOs that have always resulted in beautiful results, tried different brands of cornstarch....nothing works, they all have the moisture on top. It's so frustrating. Does anyone have any suggestions? I'd greatly appreciate it, I'm pulling my hair out here. Thanks!
