A Fondue is basically a pot of hot oil. The people who take part in a Fondue meal get long thin forks, which they use to pin pieces of meat or other things on and then fry that in the hot oil. Fondues tend to take a long time, make a big mess and lots of fun. In Swiss they also have cheese fondues, they melt cheese in the pot instead of oil and dip roasted bread or other matching things into the cheese. This makes even more mess and fun.
