Have some beef and some ground beef marinating to smoke tomorrow. I am using an MES 30. I don't know what to do about the water pan. I know if I put water in the pan, the meat will not dry as well. If I leave the pan out, the heat will fluctuate quite a bit. I thought about lining the pan with foil but am afraid grease will accumulate in the pan and burn. I intend to keep temperatures low and it may not be a problem. Would appreciate any thoughts.
