Is It Still Cheese?
Leave a slice of American cheese on a windowsill and after weeks it will dry, darken in color and curl. But rarely will it mold. Individually wrapped orange cheese slices melt smoothly on burgers and taste great straight from the package, but in most cases these soft slivers of heaven aren't technically "cheese" at all. More likely, they fall under the title of "pasteurized process cheese," "pasteurized process cheese product" or "pasteurized process cheese food."

AND THAT'S FOOD FOR THOUGHT!
