Preheat your oven to 450 degrees
Pat the tenderloin dry with paper towels and season all sides with the garlic powder, onion powder, cumin, salt and black pepper
Add 2 tablespoons of olive oil into a cast iron skillet placed over medium to medium high heat
Sear the tenderloin on all sides to form a golden brown crust
Add 2 cups of apple cider into skillet and use a wooden spoon to work up any browned bits from the bottom of the skillet
Transfer the skillet into the 450 degree oven and cook for 12-15 minutes or until the pork’s internal temperature reaches 145 degrees
Transfer the tenderloin onto a cutting board and cover with foil and a kitchen towel to help it stay warm
Place the skillet over medium heat and bring the cider to a simmer
Add a tablespoon of pure maple syrup, a tablespoon of dijon mustard and a tablespoon of butter
Whisk 1/2 cup of chicken or beef stock with a tablespoon of cornstarch until smooth and add this into the skillet
Simmer the sauce until slightly thickened and then remove from the heat
Slice the tenderloin and drizzle with the sauce
Enjoy!
