In one of the facebook groups I saw a guy say (and show pics) of where he put a small log of wood inside the grill right next to the burn pot. Has anyone tried this with lump charcoal? In theory it seems like it would work to me, but not sure how long you would have to preheat to get the charcoal to start to burn. Just looking for a way to get charcoal flavor on higher temp short cooks.
