Did a long cold weather smoke recently (15 hours and had to add charcoal 3 times). To keep temps up I had to crack the lid to get more oxygen into the WSM. When the pork butts were finished I pulled them and there were black granules on the outside of the foil wrap. When I went to close the lid vent the dial spins all the way around - the little tabs that go into the vent holes that limit movement were gone. I can’t imagine the little tabs got hot enough to melt, but this old simple mind is stumped as to what happened. Anyone seen anything like this before?
