I'm working on planning an event at work, and we want to do chocolate and caramel dipped apples. (it's a fall themed event) The problem is that I need the dipping sauces to stay hot for the length of the 3 hour event, so that people can come and dip their own as they please. So, my question is, can you put a chocolate sauce in the crockpot? I'm afraid that it would burn on the sides after awhile, even on low, since I know chocolate burns easily. Any opinions or recipes? What type of chocolate should I use? TIA!
