I don't have a specific recipe. I just take a bunch of different types of cheeses that I like and melt it. I know it's not real fondue, but my family loves it. For spice I'd add some of the sliced peppers in a jar.
Alton Brown did a show on cheese last night. His fondue recipe included simmering white wine, curry powder, and handfuls of (mostly) Gruyere and a little shredded Gouda, and a couple of other spices, I think. Sorry, can't remember which ones!
