   4.Place a medium nonstick saucepan over medium heat and add flour-milk mixture. When milk is warm, add Swiss cheese and stir quickly and frequently with a wooden spoon until cheese is completely melted and incorporated. Add cheddar cheese and continue stirring until cheese is completely melted and mixture begins to thicken slightly. (Since stovetops vary in temperature and sauce is delicate, mixture may separate. If sauce separates or if cheese doesn't fully combine, add the warmed mixture to a blender or the bowl of a food processor fitted with a chopping blade. Process until smooth and combined, covering blender or food processor lid with a towel in case hot liquid splashes. Add cheese sauce back to saucepan over medium heat and stir constantly until warmed through.) Stir in cooked macaroni, then transfer mixture to casserole dish.
