Nanshui, Guangdong — invented 1888; now exported worldwide as a cornerstone of Chinese cooking
Hao you: invented in Guangdong in 1888 by Lee Kum Sheung when oysters being cooked for soup were forgotten and reduced to a dark, rich concentrate. Oyster sauce is now the defining condiment of Cantonese cuisine — used in stir-fries, braising sauces, as a finishing glaze, and as a dipping base. Made from concentrated oyster extraction, soy, and sugar.
Sweet, briny, deeply savoury, caramelised oyster essence — the Cantonese umami cornerstone
{"Add oyster sauce at the end of cooking — high heat destroys delicate oyster flavour","Use sparingly — it is intensely flavoured and sweet","Dilute with stock for braising sauces; use undiluted as a finishing glaze","Never substitute with hoisin sauce — the flavour profiles are completely different"}
{"Classic application: steamed vegetables (gai lan, bok choy) drizzled with oyster sauce and sesame oil","Combine with light soy, sugar, and sesame oil for the standard Cantonese stir-fry sauce","Best quality oyster sauce: Lee Kum Kee premium (gold label) or equivalent"}
{"Adding early in cooking — destroys the oyster flavour","Substituting hoisin — very different flavour profile despite similar appearance","Using too much — overwhelms the dish with sweetness"}
