I put on 3 - 7# Pork Butts at 5:30 this morning. It is now 9:30. The internal on the butts are at 133. I know it is recommended we get to 140 in 4 hours. This is close but not quite there. I know what caused the problem. After I put them on I went back to bed for a couple of hours. The chamber temp had dropped to 195 when I woke up. Got it back up to 245 which is where it is now. I think the 140- in 4 is a guideline and not a drop dead rule. At least I am hoping so. Any suggestions? I would hate to have to throw these out but I also would hate to get sick...
