I make fondue for Christmas Eve dinner and there's invariably leftovers. It's a favorite of one of my nephews in particular who's always looking to snack on it on Xmas morning, but with all the activity going on, I've never had time to figure out a quick way to remelt it satisfactorily.
Would the microwave work? Double boiler? Will it be OK if it's refrigerated overnight, or would it be better to let it sit at cool room temperature overnight?
