Pork tenderloin stuffed with apple, maple and sage

Preparation

1. Preheat oven to 180°C (350°F), rack in middle position.
2. In a skillet over medium heat, brown the apple wedges in half the butter for 2 minutes, stirring gently. Add maple syrup, stir and cook for 1 minute. Add mustard and stir again. Allow to cool.
3. On a work surface, spread the pork tenderloin and cover with the cooled mixture. Sprinkle with chopped sage, then season with salt and pepper. Roll up tenderloin and tie with butcher's twine.
4. In a skillet over medium-high heat, sear the pork tenderloin in the remaining butter for 1 minute on each of the 4 sides, then transfer to a baking sheet. Bake in the middle of the oven for 12-14 minutes.
5. Meanwhile, in a small saucepan over medium heat, combine sauce ingredients and simmer until reduced by a third.
6. Remove fillet from oven and let stand for 5 minutes before removing string and slicing. Serve with your choice of mashed potatoes or roasted squash.
