I suspect the above writeups are the opinion of people who have not had real american cheese, but only the Kraft Variety of Cheese Food and Imitation Cheeses which are labeled as American Cheese. While these plastic wrapped singles of cheese like stuff do actually contain cheese, they are not in fact american cheese. They are a blended mixture of cheeses and additives designed to give a taste similar to american cheese.

If you go to a real deli or cheese shop and ask for American Cheese, you will not get plastic wrapped molded squares of processed cheese. You will get real American Cheese, which bears a mildly similar flavor to Kraft Singles, only much much better and with actual flavor. So please, before you write off american cheese, at least try the real thing.
