Prepare the Cheese: Grate the Gruyère and Emmental cheese, then mix with cornflour to help stabilize the fondue.
Prepare the Pot: Rub the inside of the fondue pot with the halved garlic clove for a subtle garlic flavor.
Heat the Wine: Pour the white wine into the fondue pot and gently bring it to a simmer over medium heat.
Add the Cheese: Gradually add the cheese to the pot, one handful at a time, stirring constantly until smooth and creamy.
Add Flavorings: Stir in the Kirsch (if using) and a pinch of grated nutmeg for extra depth of flavor.
Serve: Place the fondue pot over a low flame to keep the cheese warm and serve with a variety of dippers like bread cubes, veggies, meats, and fruits.
