Trying to use and make chocolate wicker Easter baskets for friends and family started yesterday and it broke and would not come out of the mold. it is an antique mold from Germany and 4". I warmed the mold tempered the chocolate and put in freezer to cool half hour before removing! Broke and lots of pieces delicious but not whole! Any advice? I have done solid molds and they come out beautifully! Thanks. Paul Michael
