Beijing Red-Braised Pork Knuckle

Place the pork hock in a large pot and cover with cold water. Bring to a rapid boil and cook for 5 minutes — this first blanch draws out blood, impurities, and any gamey smell. Drain and discard the water, then rinse the hock well under cold running water and pat it completely dry. Heat the vegetable oil in a large heavy casserole or Dutch oven over medium-high heat. Sear the hock on all sides, turning carefully with tongs, until the skin is golden-brown all over — about 8–10 minutes. This step builds colour and deepens the flavour of the final braise.

Add the dark soy sauce, light soy sauce, Shaoxing wine, rock sugar, star anise, cinnamon sticks, ginger slices, and dried tangerine peel to the casserole. Pour in enough cold water to come about two-thirds of the way up the hock — you don't want it fully submerged, as the steam does part of the work. Bring everything to a boil over high heat, skimming off any foam that rises to the surface.

About 5 min

Once boiling, drop the heat to the absolute lowest setting your hob can manage — you want barely a tremor on the surface, not a rolling simmer. Cover tightly and braise for 3 to 3.5 hours, gently turning the hock over halfway through. Resist lifting the lid more than once or twice. The hock is ready when the skin looks deep mahogany and wobbles like set jelly when you prod it, and a chopstick slides into the thickest part of the meat with no resistance. The kitchen will smell extraordinary.

Using a wide spatula and a large spoon, lift the hock out of the braising liquid very carefully — the skin is delicate and can tear. Set it on a warm serving plate. Strain the braising liquid through a sieve into a wide saucepan and bring it to a furious boil over high heat. Cook it down, stirring occasionally, for 10–15 minutes until it reduces to about a quarter of its original volume and coats the back of a spoon thickly — it should look glossy, dark, and move slowly like a syrup.

Arrange steamed bok choy or a mound of white rice underneath the hock on the plate. Pour the hot, glossy reduced sauce generously over the top — it should pool around the base and coat the trembling skin in a dark, sticky lacquer. Bring the entire plate to the table whole. The joy of this dish is pulling it apart communally with chopsticks, taking the tender meat, the silky gelatinous skin, and the connective tissue that has melted to a glossy, collapsing richness.
