Tony B, no problem with the hard, level surface. I did a big batch of babyback ribs yesterday, specifically to pay attention to the ramping up of the heat and keeping the heat low, around 225*. The ramping up went quite slow as I did not want to, again, overshoot the goal and then be unable to effectively bring the KK down to the desired temperature. So if anything, the ribs were relatively under-cooked for the first hour.
I also decided to experiment with just straightforward cooking for four hours, instead of using the 2/1/1 method. So while the ribs finished around 225-240*, they were cooking at a lower heat initially. In the first photo, the ribs are covered with the rub and ready to go in the smoker. I forgot to take "after" pictures until they were already plated, but you can see the two angles that the ribs were nicely cooked. I do think that the 2/1/1 method produces slightly more moist and tender than a straight four-hour cook as you see on the plate. However, they were not dry and not tough- good "tooth" feel.
One thing I did nearly by accident was a VERY good rub application: I was using my favorite Dizzy Pig rubs and I had about 1/4 of a bottle of of Jamaican Firewalk that needed to be used up- I mixed that 50/50 some Dizzy Dust. AS you can well imagine, the Firewalk has a significant presence of scotch bonnet (habanero) pepper. It really popped up the flavor of the ribs and married beautifully with the smoke and sweet pork. HIGHLY recommended. (We had some potato salad and coleslaw left over from the weekend...it was an easy and delicious meal.)
