How it behaves in this recipe
Thai fish sauce (nam pla) is lighter and less pungent than other fish sauces, with a slightly sweeter profile. It's used in small amounts to add salty umami depth to dishes. When substituting, you need to replicate both the saltiness and the subtle sweetness that's characteristic of Thai fish sauce, which is why the soy sauce + rice vinegar + sugar combination works particularly well.
Tips
