MUSTARD RUB FOR PORK LOIN RECIPES

Steps:

• Pat the tenderloins dry with paper towels.
• Combine the remaining ingredients in a bowl and stir. Add pork tenderloins and turn to coat well with marinade. Marinate for 15 minutes or as long as overnight.
• Heat a large cast iron skillet or grill pan over medium-high heat until smoking. (Alternately, heat a charcoal or gas grill to high; bank coals or turn off burner on one side.) Season tenderloins with salt and pepper. Brush pan with olive oil and add tenderloins; reduce heat to medium-low. Cook, turning tenderloins every 3 to 4 minutes, until deeply caramelized on all sides and until desired internal temperature, about 20 to 25 minutes. (You can also broil the tenderloins in the oven — about 10 minutes on one side, then turn and cook about 5 minutes on the other.)
• Remove and lightly tent with foil; let rest about 10 minutes before cutting into 1/4- to 1/2-inch slices.

Steps:

• Preheat oven to 425 degrees F.
• Combine 1 tablespoon mustard, salt and pepper in a small bowl; rub all over pork. Heat oil in a large ovenproof skillet over medium-high heat. Add pork and brown on all sides, 3 to 5 minutes. Transfer the pan to the oven and roast until an instant-read thermometer inserted in the center registers 145 degrees F, about 15 minutes. Transfer to a cutting board and let rest for 5 minutes.
• Place the skillet over medium-high heat (take care, the handle will still be hot), add vinegar, and boil, scraping up any browned bits with a wooden spoon, about 30 seconds. Whisk in maple syrup and the remaining 2 tablespoons mustard; bring to a boil, reduce heat to a simmer and cook until the sauce is thickened, about 5 minutes.
• Slice the pork. Add any accumulated juices to the sauce along with sage. Serve the pork topped with the sauce.
