Homemade Macaroni and Cheese

16 oz. elbow macaroni
1/2 cup butter
6 tablespoons flour
2 cups milk
8 oz grated cheddar cheese (sometimes I double this)
1/4 cup more milk
1/2 teaspoon garlic salt
1/2 teaspoon salt
1/2 teaspoon pepper
Parmesan cheese

Cook macaroni. Make white sauce by melting butter in small saucepan over low heat. Remove from heat add flour. Stir over heat till bubbly. Add milk and stir over heat until it has consistency of thick cream. Remove from heat, add cheese. Stir over heat till it melts completely. Add extra 1/4 cup milk. Add salt, garlic salt and pepper. Pour cheese sauce on macaroni and sprinkle with Parmesan cheese.

Macaroni with a twist
Replace half the cheddar cheese with Monterey Jack cheese. Add several drops of hot pepper sauce when you add the other spices.
