I don't know about candy melts, but I have dipped candy centers in melted chocolate mixed with parafin (according to an old recipe I have for Kentucky Burbon balls) -- I was told the paraffin is so the chocolate hardens (I use the semi-sweet chocolate). The candy I have made is delicious -- but I have thought to try the candy melts. I have read the discs melt better and don't need paraffin.
