Chop the cheese into 1 inch cubes. Put the wine, cheese, and garlic into a fondue pot (preferably ceramic). Heat over a medium flame, stirring constantly until the mixture melts and mixes. Add the cornstarch and the grated nutmeg, mixed into the kirsch. Let the whole cook 2 or 3 more minutes. Add the baking soda and proudly carry your work of art to the table where you will complete the seasoning with pepper or paprika. Bon appetit.
