It’s easy to build a simple cooking fire designed to hold a pot over the flames. Scrape out a firering and place a pair of 3- or 4-foot-long logs so they are parallel to any prevailing breeze. If there’s a downside to this cooking fire, it’s that the supporting logs are flat on the ground and can stymie the flow of fire-feeding oxygen. Build a fire on the downwind end of the logs and burn it down to coals. Now scrape most of the coals to the other end of the logs, which will serve as supports for a fry pan, Dutch oven, coffee pot or, if you’re a real throwback, a sharp stick threaded through meat. Any prevailing breeze will help fan the flames of the cooking fire, and you can build up a heat- and light-giving blaze on the coals of the first fire.
