This is my version of an all-American classic. It is one of my ultimate favorite comfort foods--sinfully rich, gooey-cheesy and tummy-warming on a chilly day. In my opinion, using varying degrees of cheddar cheese creates the perfect flavor combination. I have experimented with other cheese combinations but usually return to the classic cheddars. After making this homemade mac-n-cheese for my husband, he was successfully converted from being a lover of boxed powdered mixes. Be advised that all diets go out the window for this one!
