Method
Each step includes heat, a visible cue, and a recovery.

Step 1 · follow the visible cue
Prepare the measured ingredients
Start with accurately portioned prawns, red chillies, and shallots. Match the listed amounts, prepare each for its own cooking time, and keep wet components away from ingredients that need a dry surface.
Look for: Nothing should enter the pan until prawns, red chillies, and shallots are evenly prepared, accurately measured, and free of unintended surface water.

Step 2 · follow the visible cue
Build the defining flavour
Wake up the characteristic aromas in belacan, tamarind, and lime. Add them in a deliberate order so strong aromatics soften without burning and delicate notes remain noticeable in Sambal prawns.
Look for: The flavourings are correctly handled when belacan, tamarind, and lime smell rounded and remain recognisable, with no black flecks, raw spice aroma, or separated fat.

Step 3 · follow the visible cue
Cook with controlled heat
Cook only as far as needed to toast and grind the sambal, cook it until fragrant, then toss dry prawns only until opaque and sharpen with tamarind. Regulate heat and exposed moisture throughout this stage instead of correcting the texture later with extra oil, sugar, or sauce.
Look for: End the main cook as soon as the prawns curl loosely, sambal coats each one, and no watery liquid gathers under them. Check the thickest or coolest part rather than judging only the browned surface.

Step 4 · follow the visible cue
Finish and verify the texture
Once the heat is off, bring in cucumber and canola oil. Stop when the prawns curl loosely, sambal coats each one, and no watery liquid gathers under them, allow only the rest required for the structure to settle, and divide Sambal prawns evenly into eight portions.
Look for: Portion the recipe once Sambal prawns holds its intended shape and the prawns curl loosely, sambal coats each one, and no watery liquid gathers under them; no excess liquid, fat, or loose coating collects around the serving plate.
