Umami's secret weapon: a little goes a long way.

Pungent fermented fish liquid; intensely umami with briny depth fundamental to Southeast Asian cooking.

Where it comes from

A staple in Vietnamese and Thai kitchens, fish sauce has been used for thousands of years, originally developed as a method to preserve fish.

In the kitchen

Used as a seasoning or marinade, fish sauce enhances dishes with its complex salty flavor, often balancing with lime or sugar for a harmonious taste.

Across cuisines

Thai

The baseline seasoning for virtually every savory Thai preparation. Pad Thai uses it in the stir-fry sauce alongside tamarind; tom yum and tom kha rely on it for salt and depth rather than added stock. Northern-style larb and Isaan-style larb plaa use it raw to dress minced meat and fish. Typically 3-season anchovy-based, about 20–25°N protein.

Vietnamese

Nước chấm (diluted fish sauce + lime + sugar + chili) functions as the all-purpose condiment for spring rolls and grilled meats. Pho broth layers it in during simmering rather than using only salt. Bún bò Huế and bún mắm (fermented fish vermicelli) push toward funkier, higher-ferment grades for regional identity.

Cambodian

Tuk trey (Cambodian fish sauce) is lighter-colored and milder than Thai versions, used in kroeung-based dishes like amok trey—where it seasons the banana-leaf-steamed fish custard—and in raw beef preparations like pleah sach ko, where it acts as both salt and mild cure. Lap khmer relies on it in its fresh herb dressing.
