This tender, juicy roast pork loin recipe is prepared with a marinade and served with an easy apricot sauce. Because the pork roast should marinate for about 4 hours, plan to start preparation early in the day, the marinade is a simple blend of soy sauce and garlic, along with seasonings, and the sauce is made with apricot preserves. Peach preserves may be used in the recipe as well. The sauce complements the pork roast beautifully. Serve this pork loin roast with rice or a noodle dish for a fabulous family meal.
