Ok, being the over concerned person that I am and still an obvious newbie...I just spent 20 1/2 hours nursing a couple 9 pound butts. They never did reach 200* (188*). They hit the 140* mark just over 3 hours into the smoke. I didn't foil until I decided to go ahead and pull them. Spritzed with a cider/vinegar mix in the gasser with pretty constant temps between 225* and 235*.
For the probes, I'm pretty confident they were spot on because I restuck them and also stuck a couple of spares I had that were accurate before I stuck them and all were within a couple degrees. I've done probably a dozen butts to this point and I did do two at a time a few weeks ago with no issues.
I guess my question is, could it be the meat? Is it safe for consumption?
