When you’re out camping and want to cook something in a pot or pan, all you really need is a way to hold the vessel above hot coals. One cheap and portable solution is to bring along a few metal shelving brackets.
In this video from Grant Thompson, we see how he uses three metal brackets to form an improvised stove that will support more than enough weight to hold a pot or pan. They only cost about a buck piece and you can pick them up at pretty much any hardware store.
Then Thompson pushes one side of each bracket into the ground above the already-hot coals in a triangular shape with the tip of each bracket overlapping. And you can use different sized brackets depending on your needs; the smaller ones work well over coals but you may need larger brackets for an active fire.
It's a simple solution that's cheap and won't add much weight to your camping gear, and was inspired by Creek Stewart's book about survival hacks, says Thompson.
