Season pork loin with thyme, salt, and pepper. Wrap and refrigerate for a minimum of four hours or overnight.
Preheat oven to 350°F. Unwrap pork loin and place into a baking dish.
In a pot, combine blueberries, water (if using fresh berries), balsamic vinegar, sugar, ginger powder, chili flakes, salt and 1/2 tsp pepper. Cook over medium to medium high heat until the berries begin to break down and let go of their juices and the other ingredients are mixed through.
Pour the contents of the pot over the pork loin.
Cover with foil and roast for 20 minutes. Then uncover and roast for another 10 minutes (approximately), or until the internal temperature of the pork loin is at 145°F.
When roasting is complete, remove the pork loin and let sit on the cutting board for 5 - 10 minutes. Slice on the bias and serve with the cooked berries and drizzle the glaze over the slices.
Notes
Nutrition facts are for a 3 lb. pork tenderloin. If you choose a different weight or different cut of meat, nutritional information can change.Use your thermometer in the thickest part of the meat to make sure it has reached the right temperature.I used frozen blueberries in this recipe. It's fine to use fresh blueberries, you'll just need an additional 1 T water.
