I've yet to find a burger that's better than just caramelised onions, blue cheese, and quality beef. I might add a leafy something out of arterial guilt, but I can't say it improves anything.
Nope. What I said was it's especially delicious with hot wings.
I can't speak for everyone, but it's been my experience that people don't tend to just hunker down and eat a block of cheese by itself. Most cheeses are meant to go with something else, unless you're Charlie Kelly getting ready for a big date.
