Roast Pork with Orange (Arrosto all’arancia)
1. Preheat oven to 350 degrees F.
2. Melt butter in an ovenproof skillet over medium heat. Add the orange juice, zest, garlic, chili powder, and oregano and season with salt and pepper. Continue to heat the sauce over medium.
3. Season the meat on all sides with salt and pepper. Add to the skillet and pour some sauce over. Place the skillet in the oven and bake for about 1-1 1/4 hour, basting frequently. The meat should be opaque all the way through. The sauce should be reduced and the meat should be golden brown on top.
4. Remove the roast to a cutting board and tent with aluminum foil to keep it warm. Rest the meat for at least 5 minutes before carving. If the sauce was not reduced to your liking, you could place the skillet over medium-high heat and reduce it while the meat rests. Serve slices of the meat with the sauce.
