Macaroni and cheese

Macaroni and cheese (colloquially known as mac and cheese and known as macaroni cheese in the United Kingdom) is a pasta dish of macaroni covered in cheese sauce, most commonly cheddar sauce. Its origins trace back to cheese and pasta casseroles in medieval England. The traditional macaroni and cheese is put in a casserole dish and baked in the oven; however, it may be prepared in a sauce pan on top of the stove, sometimes using a packaged mix such as became popular in the mid-20th century. The cheese is often included as a Mornay sauce added to the pasta. It has been described as "comfort food".
