The last few pork loins I've smoked have been tasty, but more than a bit on the chewy side. Last night I tried an SV approach. The loin had already been dry brined, vac sealed and frozen a few months ago. Dropped into SV at 140F for 4 hours. Chilled in ice water bath, seasoned with pork rub, and then onto the smoker at 250F until it reached IT of 130F. Really came out perfect. Tender but not mushy, and really juicy. The SV bag had virtually no liquid in it after 4 hours, I don't think it lost a drop in the smoker. Also picked up plenty of smoke flavor even after being fully cooked in the SV. Probably do it this way from now on.
