So I got a really great bark on my rib cook this time that I didn't have before. I wonder why exactly that happened. I know you don't want to use too much wood or you'll get a funny taste. But these were perfect with a nice crispy bark. I used ozark hickory and I think I used a little more than previous cooks which is why I got the great bark. Any thoughts on bark for ribs? I smoked at 225 for four hours on a 14.5 with Royal Oak Charcoal.
