I was watching a survival show where two people burned a snake. In the show I was watching two survivalist found a snake they were going to eat and ended up cooking it to the point that it burned and wasn't edible. From what I know about cooking food over a open fire is that it's the same as broiling. You cook the meat close to the fire in the beginning to get it crispy then move it further away from the fire and cook it the rest of the way. This will cause your meat to be crispy on the outside then tender and well done on the inside.
