Ok, y'all can laugh at me, but I've actually used a (sort of) similar process on spares with good results. We were going to a dinner party and I volunteered to bring ribs. As I wanted to finish them in the mini
WSM, and we'd have to bring it with us, I didn't really want to have to clean it out, load it in the car etc.... at the last minute. So, I cheated. Cleaned out the
WSM and got it ready to travel the day before. Then on the day of, I rubbed the ribs and put them in a foil roasting pan with some beer and cider vinegar. Meat side down. Covered tightly with foil and baked at 275 for about 2 and a half hours. Out of the oven, into the car and over to the friend's place, fired up the mini with a full chimney of lit natural briquettes and 5 chunks of hickory. I wanted a LOT of smoke, and it wanted between 275˚ and 300˚. I put the wood in first, then dumped the coals on top. Vents wide open. I had forgotten to bring the ET-732, so I was guessing on the temp, but the smoke got thin and blue in about 15-20 minutes and I shut all the vents to about half. About an hour and 15 minutes later, I basted them with sauce, and 20 minutes later they were done. Quite good, tender, juicy and not falling off the bone. And plenty of smoke flavor.
