Here's how I make baked mac & cheese. I get the cheapest mac & cheese mix I can find. Then, boil the macaroni in salted water. Drain. Butter a casserole dish. In dish, mix with a fork, powdered cheese from mix, an egg, and 1/2 cup milk. Pepper to taste. Add cooked noodles and 1 cup grated cheddar cheese. Mix again with fork. Add enough milk to meet top of noodles. Stir again with fork. Sprinkle 1/2 cup grated cheddar cheese on top and dot with butter or margarine. Bake uncovered at 350 for 1/2 hr. Yummy.
