I swear by homemade mac and cheese. I know that many people love the easy boxed version, but I remember the joy of eating the baked version, topped with a sprinkling of bread crumbs, when I was growing up. This particular recipe embodies 1950s home cooking because of the Velveeta cheese, a versatile, mild cheese popularized during the ’30s, ’40s, and ’50s that pro duces a kid-friendly dish.
