Hubby's Homemade White Mac & Cheese
1 (16 oz.) package penne pasta
3 Tablespoons butter
2 Tablespoons flour
1 1/2 cups evaporated milk
1/4 teaspoon salt
1/8 teaspoon paprika
1/4 pound processed cheese (like Velveeta) cubed.
1/4 pound provolone slices or cubes
Prepare pasta according to directions on package.  Drain and set aside.
In a large pan on medium heat, melt butter. Add flour, stirring constantly until mixture thickens.
Add milk, salt, paprika and cheese.  Stir constantly until the sauce thickens but is smooth.
(The cheese sauce should resemble and extra-thick cream) If mixture is too thick, a little more milk can be added.  Pour the drained pasta into the sauce and gently stir.  The sauce will thicken as it cools.
