Back in the late 1960's, our Swiss au pair brought back a funky fondue set. I remember it well: a beaten copper affair, raised on a nifty wrought iron stand.
I happen to think that the best fondues use authentic cheese recipes. Recently, however, a bad, mad, and dangerous tendency has crept in for sickly, over rich chocolate fondues with cake, strawberries, sweeties, and the like. Please avoid them at all costs.
Here's how to make a genuine Swiss cheese fondue: grate ½ llb of Swiss cheese (Emmenthaler is ideal), and ½ llb of Gruyère into a pan. Start melting the cheese on a medium heat. It's important not to boil the cheese, over-stir it, or let it get cold. All these things will encourage separation and stringing.
When the cheese, flour and mustard have melted down, add a cup of dry white wine, a generous dash of Kirsch, a squeeze of lemon juice, and some grated nutmeg. That's it.
You then dip in hunks of fresh white bread into the cheese sauce. Traditionally, if you loose your bread in the cheese, you're supposed to pay a forfeit. Having seen The Stepford Wives, I can imagine the sort of saucy things our parents got up to forty years ago, though I stress that in our family, the forfeit was always a bottle of Kirsch.
