I decided to try another round of babyback ribs for my son and grandkids. I found a bag of Stubbs bricketts at wally world, so I thought I would give them a try. I put my usual rub on 4 slabs and put them in the fridge on wed night. I probably left them in too long. I started the smoker at 4:30 on Thursday afternoon. I used the tin can method of lighting the charcoal. Filled the water pan with hot water. After temp got to 200 I closed two of the vents to 30% and the 3rd to 50. The temp went up to 245. I had a remote temp probe on the top rack. Put the ribs in two rib racks and put one on each rack. Within 20 min the temp started dropping. Outside temp was 20 degrees and slight wind. I opened all the vents to 3/4. Temp continued to drop. I got out my welding blanket and wrapped the center section. Within 20 min the temp was 280. I closed the 2 vents on the windy side and closed the 3rd to 25%. Temp stayed at 248 for the rest of the time. I foiled the ribs and added some apple juice at the 2 hour mark. Ribs cooked for another 75 min. Removed from the foil and put them back on laying flat for 45 min. Sauced them and let them cook for 30 min. Pulled them and foiled for 15 min. The ribs had only a slight smokey taste and not much of a smoke ring. One of the ribs seemed tough. Put them in the fridge overnight. When I cleaned up the smoker Friday morning, I noticed what I think was the prob. When I checked the charcoal pan the only area of charcoal that had burned was directly in front of the open vent. Most of the charcoal in front of the closed vents hadn't light. I had used 2 chunks of hickory and 2 of apple spaced around the ring. The wood near the two closed vents was barely scorched on one edge. Basically I had only used one chunk of wood to smoke for 4.5 hours. I had probably dumped half of a 15lb bag of charcoal into the ring to cook. Just estimating I probably only used 3 or 4lbs in 4.5 hrs. I baked the ribs for an hour at 250 when we got to my sons on Friday. Ribs were tender and seemed to have a bit more smoke flavor. Everyone pigged out so either they were good ribs or the kids were starving. Just thought I would share my latest. 3 smokes and still lots to learn.
