Can anyone tell me why when I dpped my cookies in melted chocolate they dried with a white film on the chocolate? Did I do something wrong? How can I prevent this from happening. I used the melt n'mold milk chocolate and melted them in a Wilton melting pot. I noticed this happened with the Bllue wilton melts also but I covered them up with sugar crystals so it did not matter but I do not want to cover these up. Can anyone help?

thats happened to me before, but not with cookies, with chocolate molds. i still have no idea why and only a few of them were like that. I would love to see if anybody knows what causes that too.

I believe this is called "Blooming"....
