Last night I made a cheddar cheese fondue from that fondue book I bought at the library sale. It was quite simple, I browned about 1/2 cup of chopped Canadian bacon, added a glass of white wine and 1/2 lb of shredded medium Cheddar mixed with a couple of tablespoons of flour. To that I added 2 tablespoons of Calvados. I served it with fresh sourdough bread, apple slices and sliced, grilled chicken and apple sausages.
The fondue turned out OK, but it was too thin and too alcoholic tasting - if you make it I'd only use 1/2 cup of wine. I also wouldn't bother with the Canadian bacon. It was good with the sausages, but it didn't work at all with the apples.
