To make a good cooking fire, consider the need for a fire for (1) warmth and light, this is the open flame and it's needed.(2) a spot for boiling, which has some flame, but not a large fire, and a spot for (3) frying or cooking. Serious pan frying or foods that need constant attention to avoid burning will need (3) for proper cooking. It's easier to control burning coals that open flame for cooking. The arrow points to wind direction, but winds can shift and that is why the rocks are in place, to contain your fire.
Keep your main fire small, your boiling fire smaller and the frying or cooking should be done over hot coals and NOT on open flames...or your food will burn. Always have a container or something near to put the fire out if it starts to spread. It is now a good idea to make a fire when the winds are high, due to the danger of a forest fire. Never leave your fire unattended, either stay with it, or put it out if you move from camp to hunt or gather food or water. An unattended fire is very dangerous.
