This is a small shelf, and honestly it should be — real fermented shrimp paste is a pungent, load-bearing ingredient that most grocery stores won't touch. It's the funk under a Thai curry paste, the backbone of Malaysian belacan sambal, the depth in a nam prik. The sellers here carry the genuine fermented block or jar, named by brand, from people who cook with it.

The Chicago SE-Asian shop carries proper Malaysian belacan — the dense, toasted-shrimp block (like Prawn & Coral brand) you grind into sambal or toast for asam laksa. Woman- and minority-owned, shipping the continental US. It's shelf-stable, so it travels fine.
Why it's worth findingMalaysian belacan in the traditional pressed block is a specialty item a regular grocery won't stock — a curated SE-Asian importer is one of the few US places to get the real fermented thing.
See it at Pandan Market →They stock Tra Chang-brand Thai shrimp paste (kapi), a respected Thai label, and note theirs was just packed and shipped — freshness matters even for a fermented product. Flat-rate shipping, from a Thai importer running since 1999. The one to get for authentic Thai curry pastes and nam prik.
Why it's worth findingA good Thai kapi is the fermented base that separates a real homemade curry paste from a jar — and it's hard to find a trusted brand outside a dedicated Thai importer.
See it at ImportFood →A long-running Los Angeles Thai grocer carrying kapi alongside the rest of a Thai pantry, shipping nationwide in 2–3 days. A solid second source when you're already ordering curry ingredients and want the shrimp paste in the same box.
Why it's worth findingShrimp paste from a working Thai grocer is stocked and turned over by people who cook with it, not left to sit as a novelty on a general shelf.
See it at Temple of Thai →This seat's open on purpose — we won't pad the list to hit a number. If you ship real shrimp paste & belacan direct, it's earned, not sold.
Add your brand →Both are fermented shrimp pastes, but the texture and use differ. Thai kapi is a softer, moist paste you scoop into curry pastes and nam prik dips. Malaysian and Indonesian belacan/terasi is a firmer, drier pressed block you usually toast, then grind into sambal. Recipes are specific — a Thai dish wants kapi, a Malaysian sambal wants belacan.
For most Malaysian and Indonesian dishes, yes — you toast or dry-fry belacan first, which mellows the raw funk and deepens the flavor (do it with a fan on). In Thai cooking, kapi is often fried into the curry paste as you bloom it in oil. Raw, it's harsh; cooked, it turns savory and round.
It's fermented shrimp — the smell is intense in the jar and while it cooks, then it cooks down into deep umami rather than fishiness. Keep the container tightly sealed and, ideally, double-bagged in the fridge. Toast belacan with ventilation. Once it's in the finished dish, the aggressive smell is gone and what's left is savory depth.
A very long time — it's salted and fermented, which are natural preservatives. Keep it sealed in the fridge and it stays good for a year or more; the surface may darken but that's normal. Use a clean, dry spoon each time so you don't introduce moisture.
