I smoked these yesterday in my MES 30 Gen 1 over pecan wood pellets in my AMNPS. I used a rib rub recipe from one of Ray "Dr. BBQ" Lampe's books. My hoped-for set point was 225° but the MES controller is has been acting up. The temp stayed mostly in the high 260s-280s, lowering at times down into the 250s. No idea what's going on. For the first few hours the right side was consistently 20° hotter than the left side. I think when the wood pellets in the AMNPS turned the maze corner and were burning in the rear of the tray that reversed matters where the left side became 10-20° hotter than the right. I cooked them a total of 5.5 hours. By the shrinkage and bend I figured they were done. For the most part they were, but that large rack on the bottom of the photo--the biggest and thickest of the three--was almost too pink near the bone. But the rest of the meat was spot on--tender and moist and fully cooked. I smoked the ribs naked--well, I was clothed but I didn't wrap the ribs. I mopped them twice. I also turned them once so that the rack half that was on the hot right side was now on the cooler left side (until the two sides exchanged temps as I stated before).The bark came out much softer than I had hoped, considering the cooking temp was much higher than planned and I didn't wrap them. I think the racks could've easily stood another 20-40 minutes but it was 7:15 pm when I pulled them and the goal was to eat dinner before 8 pm. Still, the look and color of the ribs was exactly what I had been going for. And they were damn good. Overall, a qualified success.
