Belacan
shrimp pasteFermented, sun-dried shrimp pressed into a dense block — the funk under every sambal, the backbone of a rempah. Toasted, it turns nutty and low; raw, it is pungent enough to clear a kitchen. There is no dish in the Malay-Peranakan canon that does not lean on it somewhere.
- GoodThai kapi (shrimp paste)
The nearest cousin and easy to find. Softer, wetter, a touch sweeter than a Penang belacan — use a little more and toast it hard to drive off the extra moisture.
- PassableKorean/Filipino salted shrimp (saeu-jeot / bagoong alamang)
Briny and shrimp-forward but barely fermented, so you get the salt without the deep funk. Drain, mash, and toast in a dry pan; accept that the bottom note will be missing.
- Last resortAnchovy paste
It is fish, not shrimp, and it reads as anchovy the whole way through — wrong protein, wrong aroma. Only for a non-negotiable weeknight, and never in a dish where belacan is the star.
