Doesn't make the slightest bit of difference. Turn it on its side to start with, if you want. But I admit, I cheat. I put 'em in a throw-away foil tub, a buck or two at Walmart.........and I pour 7-up, a whole can, to start with. Now, with liquid smoking, you have to turn them sometimes because the part covered by liquid won't brown correctly. But usually just once. Spritz with apple juice at the end.
