Air-Roasted Pork Tenderloin (Chinese Roast Pork)

Recorded June 23, 2010. This method adapts a traditional roasting method used widely in China to a conventional kitchen oven. No need to baste; the flavor has already penetrated, and the low heat and wet environment keep it tender and moist.
 
Marinade

2 T minced garlic
1/4 c soy sauce (Kikkoman®)
2 T hoisin sauce
1 T rice wine vinegar
2 t dark sesame oil
1 t brown sugar
1/4 c water
Orange, lemon, or tangerine zest, or grated ginger root (optional)

Trim any fat, cut away the silver skin, rinse, and pat dry two pork tenderloins. Place pork into a sliding tab 1 gal plastic bag and pour in marinade. Lay bag flat to cover meat and place in tray to catch any chance spills. Marinate in the refrigerator for 6 to 10 hours, turning occasionally. Remove meat from bag, wipe surface dry, and discard the used marinade. Preheat the oven to 300 degrees F (150 C). Form or purchase eight metal S hooks. Place an oven rack in the 2nd highest position, and, using the hooks, hang the meat from the rack. On the lowest rack, place a pan to hold water. Fill the pan about 3/4 inch deep. Roast undisturbed for about 80 to 90 minutes. Remove from oven and let cool. Slice across, and serve garnished with sesame seeds, as part of a festive Chinese meal, or use in dishes such as soups, stir fries, rice or noodle or vegetable salads, and the like. Store unsliced and loosely wrapped in the fridge, or wrap tightly and freeze.
