Why did that hamburger taste SO GOOD?

We were camping. We made hamburgers. Rick cooked them over the campfire on a grill he made himself.

Only problem with the grill is that it’s too high. The burgers were taking FOREVER. So he put the burgers in the basket you see on top of the grill and held them directly in the firewood flames for a while.

When he pulled them out and put them on the serving platter they were SO juicy! The first bite I took…oh, it was SO good! I have never tasted such a good hamburger.

Then I noticed…they were rare. Very rare. I’ve never had a rare hamburger before. That had to have accounted for it, but why?
