All of my experience with smoking has been on an offset smoker. About a month and half ago I got a BGE. When I got it I got a plate setter for indirect heat. Now for for smoking I've always have used a water pan underneath my meat to catch drippings and for stabilizing the heat. Is it still needed for the BGE or can I go without a water pan? If I don't use a waterpan what should use to collect the drippings?
