Pork Butt. Brought the IT up to 165, and was going to foil it, and bring the IT to 203. So...IT hits 165. I foil, pop the Mav back in and what happens? The IT goes to 150. I spend the last hour waiting for it to go back up to 165. Is this normal? Why would it drop 15 degrees? I added apple juice to the foil, with some wine and garlic and spices, and they were all cold, but that shouldn't have done it. Any guidance or advice? This happen to anybody else?
