American cheese is a common processe cheese. It is orange, yellow, or white in color and mild in flavor, with a medium-firm consistency, and melts easily. It has traditionally been made from a blend of cheeses, most often Colby and Cheddar. Today's American cheese is generally no longer made from a blend of all-natural cheeses, but instead is a processed cheese (i.e. it is manufactured from a set of ingredients such as milk, whey, milkfat, milk protein concentrate, whey protein concentrate, salt) which meets the legal definition of cheese.
