Hezhe Stir-Fried Fish Floss

Called Itsahan in the Hezhe language, 炒鱼毛 is the fish-based answer to pork floss (肉松) beloved across Han Chinese cuisine. The Hezhe people, inhabiting the Songhua, Heilong, and Ussuri river networks, developed this preservation technique to extend the abundant summer fish catch through the long northeastern winter. Fresh fatty river fish — grass carp, carp — were steamed, hand-shredded, and stir-fried with white sugar until all moisture was driven off, yielding a product that kept for weeks without refrigeration. Beyond the household staple, 炒鱼毛 became the quintessential Hezhe Spring Festival gift: families prepared large batches for relatives as a gesture of abundance and care. The Hezhe full-fish banquet (赫哲族鱼宴), of which this dish forms a key part, was designated a Heilongjiang provincial intangible cultural heritage item in 2019 (黑龙江省第六批省级非物质文化遗产代表性项目).

Feather-light and golden, each strand dissolves on the tongue with gentle sweetness and deep savoury fish flavour — nothing like canned tuna; this is true floss, airy and wholly unlike any other fish preparation.

Sustained stir-frying over moderate heat drives the fish's water content below 5% water activity, inhibiting microbial growth and preventing rancidity — the same preservation principle as pork floss and beef jerky. The Maillard reaction between the fish's amino acids and the added white sugar at temperatures above 140°C produces the golden colour and characteristic toasty-sweet aroma. Prolonged heat causes the myofibril bundles in the fish muscle to separate and fan out, creating the characteristic fluffy, cotton-like texture.
