Lijiang Black Pea Jelly

The earliest written record of Lijiang black pea jelly appears in the Qing dynasty Lijiang Prefectural Gazetteer (《丽江府志》, Qianlong period), which lists it simply as "食黑豆腐" — black tofu food. The ingredient — locally called 鸡豆 (literally chicken pea) or 兵豆 — is a variety of lentil (Lens culinaris) grown at elevations of 1,700–2,450 metres in Lijiang's Yulongshan foothills, known for its dark skin and high protein content. One family lineage, the He (和) family of Yulongxian's Mingyin township, has documented six consecutive generations of 鸡豆凉粉 production, with the family's earliest recorded ancestor in the trade serving under the jurisdiction of the Mu-clan tusi (木氏土司) during the Qing dynasty. In 2018, He Zhixing (和之星) was formally recognised as the municipal-level intangible cultural heritage representative inheritor of "纳西族鸡豆凉粉制作技艺."

The cold version arrives as a tangle of slate-blue-grey strands with the quiet wobble of set custard. A chopstick press reveals surprising firmness. The jelly itself is gently earthy and faintly sweet — the pea's personality understated but distinct. The chili oil brings heat and colour, the pickled vegetable a cutting sourness, and sesame paste a nutty depth. In winter, the pan-fried version is a different creature entirely: crisp gold shell encasing a molten, almost creamy interior.

The jelly sets through starch gelatinization: lentil starch granules (primarily amylose and amylopectin) absorb water and swell when heated to 65–80°C, then form a continuous three-dimensional gel network as the suspension cools. The dark skin of the 兵豆 leaches anthocyanins into the slurry during soaking, giving the finished jelly its characteristic blue-grey hue — a colour marker of authenticity that paler substitute legumes cannot replicate. The traditional stone-grinding method (rather than steel blades) preserves more intact starch granules, producing a smoother, more elastic gel; high-speed blending damages granule structure, weakening set.
