This method is actually the most practical for cooking in a pan or pot. You gain a central point of heat versus the old campfire and grill. Their are similar methods such as a fire stack. The log stack and the janga stack. All serve the same purpose by delivering the same outcome. You may also use a peg or stake post method, where the stakes are close enough to hold a post or pan on end, basically all the same method. Only limited by you creativeness you can achieve the end goal, to cook some grub! So next time your going camping try one of these ways of cooking and enjoy the method I prefer most. Plus you save wood this way.
