How to Make It
In a medium bowl, toss the cheeses with the flour. In a medium saucepan, bring the wine to a simmer. Add the cheese mixture and cook over moderately low heat, stirring with a wooden spoon, until the cheese is melted and smooth, about 5 minutes. Stir in the Kirsch, nutmeg and cayenne and season with salt. Serve hot, with crusty bread.
