Any dry white wine will serve in a pinch, and the Switzerland Cheese Association, in broadcasting this classical recipe, points out that any dry rum, slivovitz, or brandy, including applejack, will be a valid substitute for the kirsch. To us, applejack seems specially suited, when we stop to consider our native taste that has married apple pie to cheese since pioneer times.
In culinary usage fondue means "melting to an edible consistency" and this, of course, doesn't refer to cheese alone, although we use it chiefly for that.
In France Fondue is also the common name for a simple dish of eggs scrambled with grated cheese and butter and served very hot on toasted bread, or filled into fancy paper cases, quickly browned on top and served at once. The reason for this is that all baked Fondues fall as easily and as far as Soufflés, although the latter are more noted for this failing. There is a similarity in the soft fluffiness of both, although the Fondues are always more moist. For there is a stiff, stuffed-shirt buildup around any Soufflé,
suggesting a dressy dinner, while Fondue started as a self-service dunking bowl.
Our modern tendency is to try to make over the original French Fondue on the Welsh Rabbit model—to turn it into a sort of French Rabbit. Although we know that both Gruyère and Emmentaler are what we call Swiss and that it is impossible in America to duplicate the rich Alpine flavor given by the mountain herbs, we are inclined to try all sorts of domestic cheeses and mixtures thereof. But it's best to stick to Savarin's "lump of Gruyère" just as the neighboring French and Italians do. It is interesting to note that this Swiss Alpine cooking has become so international that it is credited to Italy in the following description we reprint from When Madame Cooks, by an Englishman, Eric Weir:
Fondue à l'Italienne
This is one of those egg dishes that makes one feel really grateful to hens. From its name it originated probably in Italy, but it has crossed the Alps. I have often met it in France, but only once in Italy.
First of all, make a very stiff white sauce with butter, flour and milk. The sauce should be stiff enough to allow the wooden spoon to stand upright or almost.
Off the fire, add yolks of eggs and 4 ounces of grated Gruyère cheese. Mix this in well with the white sauce and season with salt, pepper and some grated nutmeg. Beat whites of egg firm. Add the whites to the preparation, stir in, and pour into a pudding basin.
