Memo Anita would often made this rich mac and cheese for family meals. She simply prepared it with slices of American cheese for a velvet-y sauce that clung to every forkful of macaroni.
In a large pot, bring the water and salt to a boil. Add the macaroni and boil until al dente, about 15 minutes.
Drain but do not rinse the macaroni.
Meanwhile, melt the butter in a large skillet on medium-low heat. Add the milk and stir until warm. Add the cheese and stir until melted and the sauce is smooth.
