It turns out there are lots of different labels and designations for 'Process Cheese'. Pasteurized Process Cheese - Cheese that has been made by melting together a bunch of cheeses (Colby, Cheddar, etc.) and emulsifiers. Singles from decent brands (e.g. Boar's Head) are tasty additions to burgers. Highly desirable meltiness qualities. Pasteurized Process Cheese Food - Like the above, but less 'cheese' and more 'approved other stuff'. Kraft singles, for example. Pasteurized Process Cheese Spread - Even less cheese, more moisture and other stuff. Designed for melting into queso, etc. Think Velveeta blocks. Pasteurized Process American Slices - Definitely not cheese. An oil based product. Meant to mimic the desirable melty qualities of Process Cheese.
