You will need:
1 cup milk
2 tbs butter
1/2 pound shredded Swiss cheese
1/2 pound shredded cheddar cheese
2 tablespoons all-purpose flour
1/4 teaspoon salt
1/4 teaspoon ground nutmeg
Simmer milk and butter in fondue pot or double boiler. If you set the cheese on an open heat source it may burn. Don't be afraid to take the cheese off the double boiler if it seems to be getting to hot.
Slice and cube the cheese that isn't already shredded.
Add Swiss cheese, cheddar cheese, 1/4 pound at a time.
Stir after each addition of cheese until melted.
Stir in flour.
If the cheese is clumping add a teaspoon of lemon juice. The acid will smooth it out.
When all the cheese has melted, stir in salt and nutmeg.
Serve with cut-up bread like french, sour dough, garlic, grain, crackers, pretzels, Tuscan.
Serve with fruit and vegetables like green apples, carrots, grapes, broccoli, mushrooms, cauliflower.
I don't have a fondue pot so I did have to reheat mine. Fondue pots come with long skewer like forks.
When eating fondue you put your mount onto the food and slide it off with your lips. It is considered unsanitary to touch the skewer with your mouth.
