1 medium size potato
butter
salt
pepper
heavy duty aluminum foil
tin can (from veggies or beans)

Clean the potato. Butter the outside of the potato really well, and season to taste.

Put potato into the tin can and cover top of can with foil. Place the tin can next to a fire pit of coals and let it set for 25 minutes, then turn can 90° and cook for another 20 minutes (do not peek at potato).

After 45 minutes you will have a perfect baked potato.
