Rub the inside of a saucepan with garlic.
Grate all the cheese or dice it and then heat it, together with the wine, the kirsch and the corn starch.
Stir until you obtain a creamy sauce, and then add the lemon juice and the herbs.
Transfer to a serving pot, over a low flame and stir regularly.
Serve with pieces of bread or baguette and pickled onions and gherkins.
