Remove silver skin on pork tenderloin. Rinse and pat dry with paper towels. Place into a large mixing bowl and sprinkle 1 pack of NOH chinese barbecue char siu seasoning mix onto meat. Add rice cooking wine. With food safe disposable gloves on, rub marinade mixture evenly over tenderloin.
Cover bowl with plastic wrap (or place into a large plastic zipper bag) and refrigerate for 4 to 6 hours (overnight is best).
Preheat oven to 350°F (176.7°C). Place tenderloins on roast rack in a roasting pan 2 inches apart (reserve excess marinade). Roast on middle oven shelf for 20 minutes.
Brush saved marinade on tenderloins, turn meat over then brush more marinade on. Roast for another 20 minutes. Meat is done when internal temperature reads 155°F (68°C). If it reads less, roast for another 5 to 10 minutes and check internal temperature again.
Set broiler on high. Broil tenderloins for 3 to 5 minutes or until a little char occurs. Remove from oven and place tenderloins on a tray or plate. Let rest for 10 minutes before slicing. Serve with rice, noodles or soup. Enjoy!
Notes
Seasoning mix vs. char siu marinade from a jar. Which is better?You can choose either one. I bought the seasoning mix ("NOH" brand). Regardless of your choice, either one will taste flavourful. The difference between the mix and the marinade from a jar is that the powdered version gives you better control of how diluted you want your marinade to be. Use as a dry rub, add a little or a lot of water to the mix to control the desired flavour outcome. The pre-made marinade from a jar is a thick, sticky sauce that you simply mix with the pork.What type of Pork should I use?Pork tenderloin, pork shoulder (aka. pork butt) or pork belly are good cuts of meat for this recipe. You can adapt your choice of meat based on preference for lean or fattier flavour.What is rice cooking wine used for?Used widely in asian dishes, this rice wine is a popular cooking liquid (made from fermented glutinous rice) that enhances or intensifies flavour and aroma in food. It's a form of salted alcohol and can be used much like other wines such as red and white wine in other cuisines. If you don't have rice wine available, Mirin is a good substitute for rice wine (keep in mind that mirin is sweeter than rice wine though).
