Rub the fondue pot with the clove of garlic. Put the Vacherin Mont-d’Or AOP and the white wine in the fondue pot and leave to melt over a medium heat whilst stirring continuously. Dilute the cornflour with the calvados, add it to the fondue, cook briefly, season and serve immediately. At the table, sprinkle the fondue with the finely chopped chives, according to taste.
