Sambal matah-inspired fresh aromatic relish

Raw by design

Sambal matah is a Balinese raw sambal made from sliced aromatics. Indonesia's tourism ministry names shallots, bird's-eye chillies, lemongrass and citrus leaves, dressed with hot coconut oil, and distinguishes it from sambals that are pounded or fried. Its account notes versions with terasi or garlic and describes the relish with chicken, fish and Balinese rice dishes. This report formula is an adaptation: it uses lime juice and coconut or neutral oil, omits shrimp paste by default and leaves the aromatics uncooked.

Shallots lead at 70 g of the 170 g batch, about 41%, sliced thinly so the lime and salt reach every piece. Chillies, 20 g, are sliced finely for heat. Only the tender centre of the lemongrass goes in, 15 g sliced very finely, because the outer layers are tough and fibrous. The makrut lime leaves are used by the gram: 2 g, central rib removed, sliced as finely as possible. Lime juice (30 g) sharpens, oil (30 g, coconut or neutral) coats everything and carries the aromas, and 3 g salt seasons and draws juice from the shallots so the relish dresses itself.

Two choices are left to the cook. The oil can be warmed gently before mixing, for flavour, but pouring warm or hot oil over raw aromatics is not a validated preservation step and should not be treated as one. And this version leaves out shrimp paste. If you want it, use a suitably cooked, ready-to-eat product and label the shellfish allergen, because the relish is not cooked afterwards.

The formula makes a small batch on purpose, and it should not be turned into a room-temperature oil preserve. Raw, low-acid aromatics covered in oil are the conditions behind a well-documented warning: the US National Center for Home Food Preservation reports that its research confirmed garlic-in-oil mixtures stored at room temperature are at risk of botulism. This relish holds shallots and lemongrass rather than garlic, and it has lime juice, but nobody has tested it, and the garlic case is the reason not to keep it in a jar on the counter. The recipe itself is untested in the kitchen and for keeping. Eat it soon after making; any remainder goes in the fridge at 4°C or colder where practical and is used within 48 hours, a planning convention borrowed from leftovers advice and never a shelf life.

Keeping the pieces sliced rather than pounded is part of the format: thin shallots, chilli, tender lemongrass and finely cut citrus leaf remain distinct in the finished relish. Lime juice and oil coat these pieces, while salt seasons them. The ministry describes hot coconut oil as part of its version; the report's formula instead makes gently warmed oil optional for flavour and does not treat warm oil as preservation. These are related preparations, not identical instructions.

The cited garlic-in-oil guidance from the National Center for Home Food Preservation concerns garlic specifically. This default formula contains no garlic, so that page is not used as a direct finding about this relish. It does not establish a process or room-temperature storage for sambal matah. The report's formula has no measured pH, water activity or keeping trial; keep it cold and treat the cited 48-hour leftovers period as general advice, not a measured life for the recipe.
