I cover a large tray with aluminum foil, placing my warming dish in the center. I put the tray on a kitchen island or table around which several people can gather. I use a warming dish with a little gel-filled canister underneath the stand that holds the dish, and I light the gel canister like a candle. I place several Hershey’s chocolate bars and one tablespoon of butter in the dish, stirring every minute. In a few minutes, the chocolate is ready for dipping. Around the chocolate, I place bowls of full sized marshmallow, a dish of vanilla wafers, a dish of graham cracker squares, and a bowl of toasted coconut. If I’m having a lot of guests, I might add dishes of crushed M&Ms, powdered sugar, sprinkles, crushed pecans, and anything else I might want. If I had one, I would try a chocolate fountain. I do add paper saucers and a stack of napkins, as well as long metal and wood skewers. Jewell
