A Brief History of Fish Sauce

On the street

Out of the corner of a traveler's eye — a tiny Saigon stall, a man in his 40s, and a practiced twist as he parcels nuoc cham into tiny plastic bags. It has been reported that nuoc mam (pure fish sauce) is consumed by 95% of Vietnamese households, and seeing those sachets stacked on a street cart makes the point in a single instant: this is not an accent, it’s the backbone. To Western palates it can be shocking, even off-putting at first; to people who live with it, it’s comfort, shorthand for home. “This is more than just a condiment,” one founder of a modern fish-sauce brand said — “it’s so good, it’s like gold.”

Simple, pungent, ancient

At its purest, fish sauce is gloriously straightforward: fish and salt left to do their slow work. Producers often use roughly three parts fish to one part salt, press the mix under weight, collect the liquid that drains off, and let sunlight and time — usually nine months to a year — coax it into umami-rich concentration. Labels may show squid, shrimp, or cartoon fishermen (one beloved label allegedly features a man lugging a giant shrimp), but the essence is the same: fermentation, patience, and a pungent payoff that seasons soups, salads, marinades and memories alike. Fermentation is having a cultural moment these days; fish sauce is part of that broader umami comeback.

Origins remain tangled

Who invented fermented fish? Historians still disagree. It has been reported that the first recorded fish sauce was produced by the ancient Greeks along the Black Sea and later transliterated by the Romans as garum, but scholars note the story is messier than the neat textbook version. Food historian Sally Grainger argues that what many call “Roman” fish sauce is actually Greek in origin, and language alone doesn’t settle the culinary genealogy. So while a Saigon stall and a Roman market might seem worlds apart, they’re joined by a long, messy lineage of preserved fish, salt and time — a humble method that keeps turning up on plates centuries later. Who knew a little bottle could carry so much history?
