The method

Step by step

  1. 1

    Prepare the curry paste by combining the soaked dried red chili, shallot, garlic, galangal, lemongrass, turmeric, shrimp paste, and salt in a mortar and pestle. Pound until a fine paste forms, or blend in a small food processor with a splash of water if needed.

    About 10 min

    Cook’s note: Ensure the chilies are well-drained after soaking to avoid a watery paste.

  2. 2

    Bring water to a boil in a large pot or saucepan.

    About 5 min

  3. 3

    Add the prepared curry paste to the boiling water and stir well to dissolve.

    About 2 min

  4. 4

    Season the broth with fish sauce, palm sugar, and tamarind paste. Stir until the palm sugar is fully dissolved.

    About 3 min

    Cook’s note: Taste and adjust the seasonings to your preference – it should be a balance of sour, spicy, sweet, and salty.

  5. 5

    Add the green papaya to the simmering broth and cook for about 5-7 minutes, or until it starts to soften slightly.

    About 7 min

    Cook’s note: Green papaya takes longer to cook than the other vegetables, so add it first.

  6. 6

    Gently add the snakehead fish pieces to the pot. Do not stir immediately to prevent the fish from breaking apart.

    Cook’s note: Adding the fish carefully helps maintain its shape.

  7. 7

    Add the long beans and continue to simmer for 5-7 minutes, or until the fish is cooked through and the vegetables are tender-crisp.

    About 7 min

    Cook’s note: Avoid overcooking the fish, as it can become tough.

  8. 8

    Taste again and adjust seasonings if necessary. Serve hot with steamed jasmine rice.

    About 1 min

Keep it good

Storage

Store leftover Gaeng Som in an airtight container in the refrigerator.

Reheating

Gently reheat on the stovetop over medium-low heat until warmed through, adding a splash of water if the broth has thickened.
