About 4 1/2 hours Bob. I think they could have gone just a bit longer. They did come cleanly off the bone and I don't like fall off the bone though SWMBO does, but i think they could have used just a bit more time.
Thank you Dustin. It was a great learning opportunity just as each cook is. This was the first time I didn't foil and I'm not sure I'll go back to it. The bark was far superior.
Thanks Barb. My wife was not home for them but I did save her some (good hubby) to try this evening. So I'll see if they get the thumbs up form the CRO (Chief Rib Officer).
