I use the Smoke n Grill all the time. I use the Minion Method for my coals. I also use a grate in my coal pan so there is a place for ash to fall. Further I do use the water pan with beer & water or other liquids to help deflect the heat and moisten the meat. Because I use the water pan my smoke coming out the top is usually a little on the white side because of the steam.
Good luck and share the pron id not the product!
