Martha shows actress Roseanne how to make cheese fondue.
Toss cheeses in a medium bowl with flour, cayenne pepper, and white pepper to coat, and set aside. Heat wine in a fondue pot over medium-low heat until it starts to bubble, about 5 minutes.
Stir in cheese mixture, a little at a time. Stir in kirsch. Continue to cook, stirring, until cheese has melted, up to 20 minutes. Stir in lemon juice. The mixture should be smooth and almost bubbling. Transfer pot to its stand set over a burner. Serve immediately with bread and vegetables.
You can also serve this with whole fruit, which can be arranged around the pot in a beautiful display. Be sure to set out knives for cutting the fruit.
