I have done all three fondues in metal fondue pots, and all have worked out beautifully. The key with cheese and choc. fondue, when using a metal fondue pot is to keep your flame pretty low. It can be done, but I would recommend 2 fondue pots anyway, and since you are going to have 2 you might as well make one enamel. The reason I like two is it helps keep the party going. Start with the enamel pot for your cheese fondue, just as that course is finishing, get your oil hot and into your metal pot. The enamel pot comes off the burner and put in the sink to soak. There ends up being hardly any time lag between cheese course and main course. Since the cheese pot has been soaking, during the main course it is easy to wash out and get the choc. course going, again leaving you with little lag time between courses and keeping you out of the kitchen as much as possible. Now, if you were at one of our fondue parties, we use 3 pots. 1 for cheese and choc. courses and 2 for main course. Oh, yeah, and a whole lot of wine.
