Cooked pizza using the double lid. I didn't get the temps I was hoping for, I think the inner lid stabilized at around 470, with the top air temp closer to 600-650F, my pizza steel running at about 550F.
However, I didn't manage to get any lump to burn, and did the cook with two chimneys full of briquettes.
Maybe I need to use lump to try to raise the temps more?
