Anhui Stinky Mandarin Fish
Huizhou (southern Anhui) — developed as a fish preservation technique for inland traders
Chou gui yu: Anhui's most famous (and notorious) dish. Fresh mandarin fish slightly fermented for 6–7 days at room temperature until mildly pungent, then red-braised or steamed. The controlled fermentation creates a distinctive creamy texture and complex flavour unlike fresh fish. Different from spoilage — it is intentional transformation.
