Condiment

Fish sauce

Also called nam pla, nuoc mam

The amber liquid that runs off salted, fermented fish — usually anchovy. It is the savoury backbone of mainland Southeast Asia, not a garnish for people who 'like fish'.

Origin

Fermenting fish with salt is an old tropical and Mediterranean trick; Roman garum is a relative.

Flavour

Funky, salty, meaty. The smell in the bottle is louder than the taste in a finished dressing.

How it is made

Small fish are layered with salt and left to ferment for months. Premium first-press is for the table; cheaper grades are for the wok.

How to use it

Balance it with lime and palm sugar — that triangle is som tam, pad thai and a great deal of nước chấm. Add it to hot food so the raw edge cooks into savoury; a cold salad can take it raw if the lime is bright. A few drops in kimchi paste or a western stew is a secret, not a flavour you should be able to name. If the bottle tastes bitter, it is a bad bottle, not an authentic one.

Storage

Pantry, cap on. The aroma fades after a year or two; buy a size you will finish.
