For the Modeling Chocolate, Melt the chocolate candy as I indicated in the first step, stir in the corn syrup. It will become very thick, almost like dough. Pour it into a bowl with a tight lid and put in the fridge for about an hour. It may look a little gritty or lumpy, don't worry. After one hour take it out and knead it for a few minutes and you have a roll-able chocolate dough.
