Mei gan kou rou is a Hakka banquet dish of pork belly braised with preserved mustard greens, the crowning course on a Miaoli Hakka table. Mustard greens grown in Guankuan Township are salted, sun-dried, and fermented into mei gan cai, then steamed for hours with pork belly until the fat is absorbed into the greens, leaving the meat rich but not greasy.
The Miaoli District Agricultural Research and Extension Station records that Guankuan Township farmers sow mustard greens each August, transplant seedlings after 25–30 days, and harvest from late October to November, processing the leaves by salting and sun-drying into suan cai, fu cai, and mei gan cai — a major local agricultural product. Nanzhuang's Lao Jinlong Restaurant, a representative Hakka banquet restaurant in Miaoli, was founded in 1963 (Republic of China year 52); its mei gan kou rou is one of the classic Hakka dishes on its menu alongside stir-fried pork with dried squid and pork intestine with ginger.
What is Braised Pork Belly with Preserved Mustard Greens
Mei gan cai is made by salting, sun-drying, and fermenting mustard greens (jie cai). Guankuan Township in Miaoli has extensive mustard green cultivation, and the mei gan cai produced there is known for its deep, rich savory aroma — recorded by the Miaoli District Agricultural Research and Extension Station as a representative local preserved product. The preparation of kou rou: pork belly is first partially cooked, then deep-fried until the skin is crisp, cut into thick slices with skin-side down in a bowl, covered with mei gan cai, and then steamed for two to three hours. When unmolded onto a plate, the salty-sour mei gan cai neutralizes the fattiness of the pork belly; after steaming, the umami of both ingredients melds and the sauce reduces to a thick, flavorful glaze — rich in taste without feeling oily.
Hakka banquet restaurants throughout Miaoli County offer this dish as a standard feature of traditional Hakka banquet menus. Established restaurants including Sanyi Shengxing Jixianglou, Guankuan Zaozhuang Ancient Garden Mansion, and Nanzhuang Lao Jinlong Restaurant (about fifty years of history) are all known for this dish. Shihnang Wanjia's Miaoli Hakka Food Map and Lighttour's "Most Authentic Hakka Food Recommendations" both explicitly include it. Another common way to eat it is to tuck a slice of kou rou with mei gan cai into a gua bao (steamed bun) — the pickled aroma of the mei gan cai plays beautifully against the soft, pillowy bun skin, a variation popular among younger diners.

Visitor tips
- This dish requires long steaming time; some restaurants need a day's advance reservation. Walk-in orders may be served a pre-made version, which is slightly inferior in flavor — calling ahead to order is recommended.
- Guankuan mei gan cai differs markedly from machine-brined products from other counties. When buying packaged mei gan cai as a gift, confirm the label states "Guankuan" or "Miaoli" as the place of origin.
- Hakka banquet restaurants are mostly family-run; Monday closures are common, and reservations are needed on busy holidays. Service often stops accepting new tables after 3 p.m.
