Not surprisingly, Oswald has come up with a few variations on his classic formula over the years. A few of his most successful wanderings:
1. If you don't mind specks, add fresh chopped herbs to the cheese mixture just before serving-chives, rosemary and parsley work best. Another alternative: leeks. "Amazing," says Oswald.
2. Sauté fresh morel or porcini mushrooms in a little butter with a few chopped shallots, then add themto the cheese. "Awesome."
3. Substitute beer for the white wine. Oswald favors King Ludwig pilsner.
