Fish sauce
Salty, savory, briny, fermented, and deeply umami.
Lens analyzedFish sauce is a salty fermented fish condiment that adds deep umami and aroma.
Where it comes from
Fish sauce is made by fermenting fish with salt, a preservation and seasoning technique found in many coastal cuisines.
Varieties — Thai nam pla, Vietnamese nuoc mam, Filipino patis, and other regional fish sauces vary in salt, aroma, and sweetness.
It is foundational in Thai, Vietnamese, Filipino, Cambodian, Lao, and many Southeast Asian kitchens.
In a modern kitchen — Use drops or teaspoons, then taste; it adds salt and savoriness at once.
Buying it
Choose fish sauce with fish and salt high on the ingredient list. Avoid bottles with muddy sediment, damaged caps, or overly sweet seasoning if the recipe expects pure fish sauce.
Storing it
Store sealed in a cool pantry or refrigerate after opening if your kitchen is warm; keep the cap clean to prevent crystallized buildup.
Keeps about 2 years in the pantry.
Out of fish sauce? Good swaps
- Soy sauce — Use a bit less for salty umami; lacks the briny seafood note, so add a squeeze of lime to brighten.
- Worcestershire sauce — Swap a smaller amount for a savory, fermented depth in marinades and dressings.
- Oyster sauce — Use sparingly where some sweetness and body are welcome; thicker and milder than fish sauce.
