Add all marinade ingredients to a 1 gallon plastic bag. Place pork tenderloins in the bag and seal. Work the marinade over the pork and put in refrigerator overnight.

Preheat oven to 350°F. Remove pork from bag and remove excess marinade from the pork. Keep marinade for later use. Salt and pepper to taste. Let sit to reach room temperature. Heat oil in a large skillet on medium high. Sear all sides of the pork and then place skillet in the oven to finish cooking. Remove pork when internal temperature reaches 140°F. About 15-20 minutes.

If needed add additional oil to the skillet the pork was cooked in. Add onion, carrot, and celery and cook until soft. Add marinade, honey, and stock and bring to a boil. Cook to reduce volume by half. About 5-10 minutes.
