Siu Yuk
脆皮燒肉·(see-oo yook)
The Chinatown Deli Window
At five p.m. under the red heat lamps of the Chinatown deli window—those gleaming, golden slabs of Siu Yuk daring you to walk by—the butcher brings a heavy cleaver down. But the real secret of the Cantonese home kitchen isn't industrial heat; it's time and cold desiccation, and by puncturing the skin, letting the fridge dry it on a wire rack over the weekend, and using an osmotic salt crust in a standard air fryer, you can pull off a weeknight masterpiece where the skin blisters, yielding that violent, shattering crunch. The rest is just carving.
Before you start
Secure a meat tenderizer tool with dozens of metal needles.
While a bundle of bamboo skewers can work in a pinch, a proper tool makes puncturing the tough skin infinitely faster and more uniform.
Ingredients
- skin-on pork belly1 1/2 lb
- fermented red bean curd cubes2 small
- Shaoxing wine1 tbsp
- five-spice powder1 tsp
- white pepper powder1/2 tsp
- granulated sugar1 tsp
- table salt1/2 tsp
- sand ginger powder1/2 tsp
- white vinegar1 tbsp
- coarse kosher salt1/2 cup
Method
- 01
Score the meat side of the pork belly, taking absolute care not to pierce the skin.
Place the pork skin-side down and make shallow cuts, about an inch apart, across the meat to allow the marinade to penetrate deeply.
- 02
Massage the aromatic paste into the meat, aggressively avoiding the skin.
Whisk the red bean curd, Shaoxing wine, five-spice, white pepper, sugar, table salt, and sand ginger powder. Rub it thoroughly into the meat and sides. If a single drop touches the skin, wipe it off immediately.
- 03
Violently puncture the skin hundreds of times with a meat tenderizer or sharp skewers.
Flip the belly over. Pierce firmly through the tough dermis to create escape routes for rendering fat, but stop just short of hitting the red meat to prevent juices from ruining the crackling.
- 04
Build a tight foil boat around the sides and refrigerate uncovered for twenty-four to forty-eight hours.
The modern frost-free fridge is a phenomenal dehumidifier. Leaving the skin exposed turns it hard and leathery—the non-negotiable secret to a blistering crunch.
- 05
Brush the skin with vinegar, bury it entirely in the damp coarse salt, and air fry at 350°F for 35 minutes.
The damp salt packs tightly, insulating the skin from burning while osmotically drawing out the last stubborn drops of moisture.
- 06
Discard the hardened salt crust, wipe the skin completely clean, and blast at 400°F for 15 minutes.
Brush away every stray grain of salt before returning to the heat. You will hear loud popping as the skin aggressively bubbles into a golden, puffy crackling.
- 07
Rest the meat for ten minutes before carving skin-side down with a heavy cleaver.
The rest allows juices to redistribute. Snapping through the skin from the meat side prevents the crackling from shattering into a million pieces.
Notes
Treat the multi-day process as a strategic weeknight advantage.
Spend fifteen minutes on a Sunday afternoon prepping and poking. Come Wednesday, the active labor is virtually zero while the air fryer does the heavy lifting.
Do not skip the fermented red bean curd.
It provides the definitive, funky, deep-savory Chinatown baseline straight from the jar. If you truly cannot find it, dark soy sauce and hoisin can pinch hit, but the real deal is worth the hunt.
Never subject leftover crackling to a microwave.
It will turn rubbery in seconds. Toss it back into a 375°F air fryer or oven for five minutes to restore the snap.
