Red-Yeast Marinated Fish

Red wine lees fish traces Fuzhou's lees tradition to the Song dynasty. The Song dynasty scholar Zhuang Jiyu recorded in his compendium 'Jiwei Bian' that in Fujian 'red lees are mixed with vegetables, fish, and meat in autumn' — evidence the custom predated any single cook or restaurant. The scholar Zhu Xi further described Fuzhou red lees as an echo of ancient fermented sweet wine, placing the tradition in a lineage stretching back to antiquity. By the late Qing dynasty, red-lees fish had become a festival staple across the Fuzhou basin, with families curing whole yellow croaker or grass carp in earthen crocks days before the New Year, then steaming or frying the fish on New Year's Eve.

The flesh pulls away in firm, wine-fragrant flakes — an immediate tang and sweetness from the lees hits before the clean fish flavor opens up. A faint warmth from star anise lingers on the back of the palate. The crust is faintly crisp from the frying, softened slightly by the braising sauce.

Red wine lees are the solid residue after pressing Fuzhou's fermented red yeast rice wine. During fermentation, Monascus purpureus fungus converts rice starch into vivid azaphilone pigments while producing protease, lipase, and amylase enzymes alongside volatile esters and alcohols. During marinating, these enzymes partially break down surface proteins and fats in the fish, allowing pigments and aromatic esters to penetrate deeply into the muscle fibers. The lees are naturally acidic, which degrades trimethylamine — the compound responsible for fishy odor — significantly reducing it. Aging the lees through summer ('过夏糟') concentrates volatile flavor compounds further. When the fish is deep-fried at high heat, the Maillard reaction transforms the lees-stained surface from brick-red to deep burnished crimson while sealing in interior moisture.
