Sio Bak with Mandarin Orange Mustard – 橘子芥末酱烧肉

We love our Sio Bak (who doesn’t!), and for this CNY season here’s a seasonal twist for you guys to cook a feast for your loved ones this reunion dinner.

In the season of mandarin oranges, we grated it’s zest on the underside of the pork belly for a citrus-ey twist, and roasted it using the Weber Q Grill for 2 hours. Brushing rice vinegar on the side every 30 minutes, the temperature is increased for the last 30 minutes to give it that shiok, crispy crunch.

We then made our own Mandarin Orange Mustard using juice from mandarin oranges, to pair with the meat. Yums!

Weber Asia is having a promotion for the Q grills : free cover & griddle worth up to $135 for every purchase, so it’s great value for a gas grill this season! –
