i'd have to say it was grilling over coals from a campfire as a boy scout. and geez does that bring back a bad memory.
i remember a particular camping trip on sandy hook island where a cold october rain soaked us for the entire three days. the wind was so bad that it whipped up the wet sand, stinging your face and getting into everything, making it even more uncomfortable.
but the worst part was that, for some ungodly reason, we brought chicken to grill instead of the usual burgers and hot dogs.
since everything was soaked and the wind fierce, we could barely keep a fire going, even inside one of the old bunkers that used to house huge cannons which protected ny harbor during the second world war.
undaunted, we still tried to cook the chicken. after an hour over what little fire we could produce, the chicken "looked" done, and we were starving so everyone just grabbed a piece and chowed down.
on burnt but mostly raw chicken, covered in sand.
i'm amazed that no one got sick from it. all of that wet sand must have killed off the salmonella, lol.
