Iconic in nature, the cheeseburger has always come standardized with American cheese. Go into a diner or a greasy spoon and you'll see the burger on the menu with the words "add cheese," which defaultly means of the american variety.
I enjoy a cheeseburger with american cheese, but sometimes I have to wonder if it really is the best compliment to a burger. What's wrong with a mild cheddar? Not something overpowering where the cheese overtakes the burger. Something light or flavorful, or something that will add zip like jack. American can have the tendency to vanish into taste non-existance, and in the end it only feels like a fatty binder and nothing else. Am I wrong to actually want to taste the cheese as well?
Sometimes I wonder if burgers I've eaten in the past would have tasted better if I just went a little anti-american and ordered cheddar.
