Sambal belacan-style fresh relish

A fresh relish built on shrimp paste

Sambal belacan is a fresh chilli relish from the Malaysian and Singaporean table, made with belacan, a fermented shrimp paste: red chillies pounded with the paste and sharpened with citrus. Belacan supplies the fermented shrimp flavour. In Malaysia it sits beside kicap, chilli sauces and peanut sauces, and a raw chilli and lime sambal and a cooked, oily sambal are different preparations. This formula is the raw kind, made for the table rather than the pan, and keeps to 90 g red chillies, 10 g prepared belacan, 35 g lime or calamansi juice and 10 g sugar. A National Library Board Singapore account describes it as a regular accompaniment in Malay, Eurasian and Peranakan meals.

Belacan is one of many fermented shrimp pastes. Belacan, terasi, kapi, bagoong alamang and their relatives share a broad family resemblance but differ in raw material, fermentation, consistency and culinary treatment, so use the paste the recipe names and follow its cooking instructions. Some products are sold ready to eat; others are meant to be cooked before use. If yours needs cooking, cook it before it meets the chillies, and never assume that every block is ready to eat. A cooked, ready-to-eat paste and one intended for cooking are not interchangeable without that step.

The proportions explain the taste. Belacan is only 10 g of the 145 g relish, about 7%, but it carries much of the savoury depth and much of the salt, which is why the formula adds none: taste first, then season. The chillies are the body. A blend of mild and hot lets the cook set the heat without changing the 90 g that gives the relish its bulk. Lime or calamansi juice, 35 g, sharpens it, and 10 g sugar rounds the citrus. Pounding rather than blending bruises the chillies into a textured relish, with juice drawn out to bind it.

The library article gives a different sambal belacan formula, attributed to a cookbook: it dry-fries the paste, pounds it with red and bird's-eye chillies, then adds lime, salt and sugar. This report's formula does not copy those amounts or steps. It uses a mild-and-hot chilli blend, lime or calamansi, sugar and no added salt, and directs the cook to follow the chosen belacan label. The shared name and pounding method do not make the formulations interchangeable.

Shrimp paste and sambal across the region

Singapore shows why it pays to think in terms of the dish and the community rather than one national sauce: sambal belacan sits beside chilli and ginger sauces made for particular dishes and soy-based dips. In Myanmar, ngapi, the fermented fish and shrimp pastes, are not one uniform substance. Ngapi yay is a watery dip, while balachaung adds fried seafood and aromatics for texture, and a prepared watery dip and a concentrated base keep differently. Jaclyn Bond's first-person account of her family's balachaung describes it, though its informal storage language is not adopted here.

In Brunei, cacah is the sour, spicy dip served with ambuyat, and the dip is fundamental to that combination; ambuyat itself is the starch, not the condiment. Sambal families run through Brunei's cooking too. In Timor-Leste, ai-manas names a family of chilli, aromatic and citrus preparations whose exact formulas vary; AMCarmen's Kitchen documents one cook's version, which is evidence of that version, not of a fixed national formula. Sambal belacan belongs in this wider landscape as one specific relish, not a stand-in for all of it.

Keeping a fresh sambal

Newly mixed, it is a fresh food. Neither the salt, nor the acid, nor the fermentation that made the shrimp paste can be relied on to preserve the relish once chilli and citrus are added, so freeze what will not be eaten soon. The quantities are untested: the relish has not been trialled in a kitchen, tasted against a Malaysian or Singaporean version or checked for keeping. In the fridge it is kept at 4°C or colder where practical and used within 48 hours, a convention borrowed from general leftovers advice and not a shelf life, or sooner if the shrimp paste's own after-opening instruction is shorter. It contains shellfish.
