2 1/2 cups uncooked pasta
2 Tablespoons butter
3 Tablespoons flour
Pepper to taste
1/2 teaspoon salt
1 teaspoon spicy brown mustard
3 cups milk
12 slices white American processed cheese
1 3/4 cup white extra sharp cheese (like Vermont white)
1/2 cup Swiss cheese
1/2 cup grated Parmesan (can be dry type)
3 Quart Baking Dish
Cook pasta - bring it to boil and cook for about 7 minutes. Drain, set aside.
Prepare thin white sauce: On low heat, melt butter. Sprinkle in flour, pepper, salt and mustard. Whisk to make a rue. Slowly add milk, whisking at the same time to make mixture smooth. Add more milk and whisk. Continue to cook on low heat and whisk often until sauce is a bit more thicker. Add cheeses but not all at once, just about 1 cup at a time and stir to melt. Once all cheeses are melted, taste and see if you want to add a little more flavor of a cheese, salt or pepper. Then add pasta into pan and stir very well to coat.
