I happened too fast to get the video. But asked for the phone and you can see what he did on his own.
Dad never wrote it down so i will tell the recipe for my dear cousin Nancy. Or any body who loves mac and cheese.
He only used Tillamook sharp cheddar cheese. For a large baking dish i used 2 .5 lb of cheese one large one lb of elbow macaroni pasta. ( my shopper got small but pasta but it tasted wonderful. next time i will try the bigger pasta.
cook your noodles, butter your baking dish,it has to be real butter for the same taste. then slice the cheese not too thin remember how much dad loved his chess. them pour the cooked noodles the on top slice more chessed and cover the noodle with cheese then pour over the noddles and cheese heavy cream then black pepper. to taste. I never use salt but salt if you wish,
bake 350 my big baking dish took 45 min in a pre -heated oven.
