Yeah, raclette machines are kind of fiddly but good fun for a dinner party kind of thing if you've got time. You stick a load of ingredients out. (I remember pre-cooked potatoes, ham, pickled onions, pretty much what someone else mentioned earlier as traditional acompaniments.) Everyone gets a tray, loads it up with ingredients, sticks some raclette cheese on top and browns it in the machine. Repeat till satisfied. I'm sure you could vary the ingredients and the cheese if you wanted to. It does take quite a while to really eat your fill though. Those trays aren't huge. You *could* have two on the go at once I spose, but then you'd need a great big machine with lots of trays, and you could probably do something similar in big batches under a normal grill.
