Heat milk on medium/high heat with a pinch of salt until milk is nearly boiling.
Lower heat to medium/low and add macaroni.
Stir macaroni every couple of minutes until the milk has nearly entirely evaporated leaving you with a thick, creamy, stew of macaroni (you will need to stir more often near the end of cooking to ensure it doesn't stick to the bottom of the pan -- once you've added the macaroni it should take about 20 minutes).
Serve with meatballs, prinskorv (small Swedish sausages) or other quick and easy meat on the side. Often enjoyed with ketchup.
