2cups944 ml balsamic vinegar (or purchased balsamic glaze)
2 1/2tablespoonsrosemaryfinely chopped

1/2teaspoonfreshly ground black pepper
Instructions
Let the pork tenderloin sit at room temperature for 1 hour.
If using purchased balsamic glaze, skip this step: To a non-stick skillet add the balsamic vinegar over medium heat, reduce heat until it simmers and reduces by half and gets syrupy. Transfer to a bowl to cool.
Preheat oven to 475°F/245°C.
Take 1/4 of the balsamic glaze and rub all over the pork. Coat the pork evenly in the rosemary, salt and pepper.
Heat a cast iron skillet over medium high heat. Sear the pork on all sides.
Transfer the pan to the preheated oven and roast for 20 minutes until the internal temperature reaches 145-155 F/63-68°C.
Transfer the pork to a cutting board and allow to rest for 10 minutes before slicing.
