I must be doing something terribly wrong with my cookshack because I have never been able to achieve bark like that with my cookshack. What temp and time range are you cooking at to get the ribs to bark up like that? I can only achieve that when I use my log burner.
I season the ribs the night before, wrap in plastic wrap and leave in fridge overnight. I don't pre-heat, I just place the ribs in the middle rack, a single block of hickory and set the temp at 225 for 5 hours. I'll start getting meat retraction off the bone at the 4 1/2 - 5 hour mark. I pull the ribs, wrap in aluminum and pour a little cranberry juice onto each rib, wrap and place back in the CookShack. I'll let them smoke for 45 mins - to an hour and pull. Unwrap foil, place ribs back in smoker and finish for 20-30 minutes.
You'll get a beautiful bark, juicy ribs falling off the bone and many compliments from your family and guests.
