Mei Cai Kou Rou: Preserved Mustard Greens and Pork Belly (梅菜扣肉)

Mei cai — 梅菜, preserved, salted, sun-dried mustard greens — is the Hakka kitchen's most important pantry ingredient. Made in autumn when mustard greens are at peak, salted, pressed, sun-dried over weeks, and stored, the resulting dark, fragrant, intensely savoury pickle has a months-long shelf life — a crucial property for a people historically resettled and displaced. Paired with pork belly in a long-steamed preparation of extraordinary depth, it is a dish that has outlasted every political change in the region where it was made.

Pork belly — whole slab, skin-on — blanched in boiling water for 15 minutes to firm the skin and remove excess fat. Removed, dried, and the skin brushed with dark soy sauce while still hot; the hot surface absorbs colour immediately and deeply. Deep-fry the slab skin-down in oil at 180°C for 8–10 minutes until the skin blisters and puckers — the blistering creates the final texture. Allow to cool, then slice through to 5mm thick tiles, each with the skin at the top. Lay skin-down in a deep bowl. Mei cai rinsed of excess salt, pressed dry, then stir-fried briefly with garlic, Shaoxing wine, oyster sauce, palm sugar, and five-spice — just enough to open the flavour. Layer mei cai over the pork, press it down. Steam 1.5–2 hours. Invert onto a serving plate — the skin is now on top, the mei cai beneath. Two hours of steam have merged the salt and umami of the preserved greens into the fat and gelatin of the pork into a single unified flavour.

Mei cai provides salt, umami, and a slightly sweet dried-vegetable complexity that deepens dramatically with steaming. The pork provides fat, gelatin, and the sweetness of the caramelised dark soy crust. White rice, plain steamed — no competition for the sauce. The pork drippings and mei cai juices pool at the base of the serving plate. They are the best part.
