Rub the inside of a fondue pot, small crock or cast iron skillet with the garlic clove.
Warm the wine in the pot. Add the cheeses, cornstarch and lemon juice. Cook over medium-heat, stirring occasionally, until the cheeses begin to melt, about 5 minutes.
Reduce heat to low. Add nutmeg and cook, stirring gently, for another 3 minutes. Serve with bread, salami, pears and apples.
Notes
Gouda cheese or Fontina cheese may be substituted for the Emmentaler, if desired.
