Fresh bread will just disintegrate- so must be 2 days old approx- and farmer's type with strong texture. Must say I am a fondue purist - bread and nothing but bread. Careful with moitié-moitié fondue- it must not be over heated or it goes thin and separates.
Best advice for a fondue is to make sure you have a good hike, ski, cycle, snowboard, etc- first and Kirsch for the 'coup du milieu' - a small tumblerful half way through.
I often serve my "Scottish Fondue" when I am catering, Isle of Mull with black beer and whisky and the best for dipping, and this goes for Swiss cheese fondue too, is not bread but roasted vegetables.... small potatoes, carrot sticks, broccoli and cauliflower heads lightly steamed, brushed in butter and bunged in a hot oven until crispy. Bread I find is just far too heavy but if you really need bread, as others have said, don't use fresh, one day old is much better and it doesn't matter what type, it's up to your taste.
My wife though likes fresh (fresh, not from a tin) pineapple dipped in her cheese fondue...
I would recommend tasteful bread, white, or semi-white with lots of crust.
I like best "Pain Paillasse" because its made with sourdough and therefore gets a unique taste. Make sure to put your breat crumbs in the hot oven for some minutes to get them some consistency and roasting flavour before dunking into cheese
You can buy Pain Paillasse for example at Bäckerei Jung, Limmatplatz.
Dont forget tons of garlic, white wine, Kirsch, etc. ... and sleep well that night.
I like grumpygrapefruit's idea of the lightly roasted vegetables. I didn't realise that there was tradition of just bread to dunk into the cheese, before I arrived in Switzerland. Until then, I had always had cut up, fresh, raw vegetables - broccoli, cauliflower, carrots, mushrooms, capsicums, radishes etc. nom nom.
This is cool! Thanks for all the ideas. I like the roasted veggies idea and crusty, slightly stale bread would work best, I think (we just used the leftover half of a loaf the other day). Now I just have to talk my wife into trying some Kirsch. :-)
Yeah, some type of baguetty bread is good - agree on the Pain Pallaise, its ideal.
Also really like pears in fondue. In fact I like that better than bread. Last week we had fondue and I happened to find a tub of fresh figs. REALLY good! Quarter them, dip them, delicious!
Boite chaude: a Mont d'Or cheese in wooden box - score the tope and insert slivers of garlic, pour a bit a wine wine over- then wrap the box in double foil and bake in the oven till runny (about 30 mins medium oven) then dip new potatoes ... and roast veg in the molten cheese.
