This video shows you how to make a slightly sweet marinade for pork tenderloin. Brown sugar and cinnamon combine with sherry, soy sauce, olive oil, and garlic powder in this simple marinade. So easy! You'll marinate the tenderloins for 6 to 12 hours and then grill them for about 20 minutes. They come off the barbeque wonderfully moist and tender.
