A pungent dark fermented shrimp paste, pounded into sambals and stews. Javanese indentured workers carried it to Suriname, and it remains the backbone of Javanese-Surinamese seasoning.
It is a long low-acid ferment of raw shellfish at ambient temperature, kept safe only by a salt ratio measured against the catch, and shellfish additionally concentrate biotoxins that fermenting does not destroy.
