Pans, Woks & Hanging Parts
For everything a grate can't hold.
Steel woks and pans for anything with liquid in it, cast iron for anything that wants slow heat, and the masts, hooks and hangers that hold them over the fire.
Cast iron keeps its heat long after it leaves the fire. Steel heats faster and weighs half as much. There's a right answer for most dishes, and it's usually the one you already own.
