About this sauce

Nam jim seafood (nam jim talay) is the bright green, very sour and very hot sauce served with grilled prawns, squid and fish at Thai beach shacks and seafood markets. Pounded green chilli, garlic and coriander root are loosened with lime juice and fish sauce, with a little palm sugar to hold it together.

Unlike sweet chilli sauce, it's raw and loud, not sticky. Unlike nam jim jaew, there's no toasted rice or dried chilli; this one is all fresh. Make it within an hour of eating so it stays green.

What to put it on

Grilled prawns, squid and whole fish, steamed mussels, oysters, crab and grilled chicken.

Spoon it over Thai steamed fish with lime, serve it with grilled sugarcane prawns or yum talay seafood salad. Read up on palm sugar and fish sauce.
