- 1 pork tenderloin
- salt and ground black pepper to taste
- 1 tablespoon olive oil
- 1 1/2 plums, pitted and chopped
- 2 tablespoons balsamic vinegar
- 1 tablespoon brown sugar
- 1 tablespoon honey
- 2 tablespoons blueberry juice (optional)
- Preheat oven to 400 degrees F (200 degrees C). Line a baking sheet with foil.
- Season the pork tenderloin with salt and pepper. Heat olive oil in a heavy skillet over high heat until the oil shimmers; gently lay the tenderloin into the hot oil. After about 1 minute, gently loosen the meat from the bottom of the skillet, if necessary. Cook until the pork is seared a golden brown color, about 3 minutes per side. Transfer the pork to the lined baking sheet.
- Roast the seared tenderloin in the preheated oven until a thermometer inserted into the center of the pork reads at least 145 degrees F (63 degrees C), about 15 minutes. Remove the pork from the oven and allow to rest for 10 minutes before slicing into medallions.
- Cook the plums, balsamic vinegar, brown sugar, honey, and blueberry juice in a small saucepan over medium-low heat, stirring often, until the plums are soft, about 10 minutes. Transfer the sauce to a blender and blend until smooth. Return the sauce to the saucepan and simmer until reduced and thickened to the consistency of apple butter, about 5 more minutes. Spoon plum sauce over the sliced pork to serve.
