Find three good sized rocks about the size of a softball, and place them in the campfire to get hot. Sometimes you get a rock that will crack when heated so it is wise to place a couple of extras in to heat, just in case. Oh yes, by the way, the rocks have to get VERY, VERY HOT!!!!!!!!This is a easy recipe that you can start and forget about for several hours. This is how it's done, and yes, it may sound rather primitive but it works!
While the rocks are getting hot take a whole chicken and clean inside and out, then rub it down with salt and pepper to taste. Stuff 2 whole celery sticks and 1 whole onion into the chicken.
After the the rocks are HOT, take a pair of B-B-Q tongs and stuff 1 of the rocks into the chicken with the celery and onion. Place the chicken on a large sheet of tinfoil and take the other two rocks and place one under each wing.
Now wrap the chicken in tinfoil, and the more, the better. Remember, if you don't use enough the rocks may burn through and/or you will lose too much heat to cook the bird.
Then take wet newspaper and wrap it around the tinfoil. Also make sure you wrap at least 10 layers of newspaper around it, although 20 or more is best. this will hold the heat of the rocks in extremely well.
And your done!!!!! The heat of the rocks will cook the chicken to a fine turn in about 3 hours, giving you time to go fishing, for a walk, or if you are like me, take a nap.
