Pork Loin is often called "the other white meat". It's super low in fat and indeed turns white when it's cooked. It is typically a large piece of meat, like a roast, and it comes from the back of the pig. That's why it's sometimes called a pork loin roast. It can come with the bone in or the bone out. And if you've never smoked pork loin, it's really easy to do and provides a lot of flavor. Pork Tenderloin is more of a filet and just like the name implies, it is the most tender cut of pork you can get. It's smaller and tends to have a darker color to the meat than the pork loin. Even when this cut of meat is fully cooked, it still has a slight pink tint, especially when it has been smoked.
