1 lb Gruyere, shredded
1/8 cup grated Parmesan
2 tbsp cornstarch
2 garlic cloves, peeled
1 cup white wine (I use something like Gruner Veltliner or a French Sauv Blanc)
1 tbsp lemon juice
1 tbsp Kirsch
1/8 tsp dry ground mustard
a healthy pinch of freshly grated nutmeg
Toss the cheeses with the cornstarch until coated. Rub the inside of a heavy duty saucepan with a clove of garlic. Discard the garlic. Rub the inside of the fondue pot with the other clove of garlic and then discard the garlic.
Over medium low heat, add the wine and lemon juice to the saucepan and bring to a simmer. Bit by bit, stir the coated cheese into the wine and lemon juice. Turn the heat to low and stir until the cheese melts smoothly and completely into the liquid. Let it thicken.
Add the Kirsch, nutmeg, and dry mustard.
Pour into a fondue pot that has been set over simmering water in the manner of a double boiler, with a heat source underneath the vessel with the water.
We like a good crusty bread, cut into cubes and lightly toasted, to dip. Baguettes work perfectly, of course, but we also really like a good, dark pumpernickel. (Make sure each cube has some crust on it, if possible.) I also love Granny Smith apples with this.
Shameless Confession: This recipe "should" serve 4 to 6, but that's only if Stuart and I are not 2 of the party!

Note: I made this with Alpage Gruyere from Antonelli's Cheese Shop here in Austin recently and it was The.Best.Fondue.Ever. I had never had the Alpage AOC Gruyere until this, and now I'm afraid I won't be able to ever go back to the ordinary.
