There was some talk today in another thread about pork loin and I was asked in greater detail what I do with them.
First off I normally get the big ones from Costco. I cut off about 6-8 inches in from each end and make them roasts. Then I take the middle section and slice them into pork steaks. I either just cook this like a pork chop (pan sear) or I cut it up and make it into fried rice.
As far as the roasts go. I put the smoker to 250° and light off a half filled smoke tube for extra smoke at the higher heat. Then I hit it with the a sweeter rub. Normally whatever I would do on ribs it what would go on pork loin. I find pork takes the sweetness. The last one I did had an asian rub followed buy an apple pie rub (both were RecTec rubs). Light coating of each. Throw the pork loin on the smoker and cook until 140° then pull and tent for a bit. At about 120° and then again at 130° I will put a light sauce on. Some sweet baby rays mixed with a little apple cider vinegar. Just a bit runny to coat the loin. Not too much flavor addition but just enough.
Loin comes out with a lovely smoke flavor and very juicy. Slice it about brisket slice thick and serve with salad and green beans (or potatoes).
That's how we do pork loin roast in my house.
