Hello all. Mods, I apologize if this is the wrong forum. Has anyone made a smoker from clay/sand or clay/sand/straw (cob)? I ordered extra clay for building my house walls, got 12 cubic yards, turns out i only need ten. I have built a cob pizza/dutch oven, and an outside fireplace. Cob has great thermal mass, so I wondered if anyone has used it for a smoker. Turning up nil on Google.
