The method

Step by step

  1. 1

    Rinse the fish thoroughly under cold water and pat it completely dry with paper towels.

    About 2 min

    Cook’s note: Ensuring the fish is dry helps the salt crust adhere better.

  2. 2

    Stuff the cavity of the fish with the lemongrass, kaffir lime leaves, and galangal.

    About 1 min

  3. 3

    In a large bowl, combine the sea salt and all-purpose flour. Gradually add the water, mixing until you have a thick, paste-like consistency.

    About 3 min

    Cook’s note: The mixture should be firm enough to stick to the fish without being too wet.

  4. 4

    Spread a thick, even layer of the salt mixture over the entire surface of the fish, ensuring it is fully covered.

    About 3 min

    Cook’s note: Don't be shy with the salt; it forms a protective crust that is discarded after cooking.

  5. 5

    Preheat your grill to medium-high heat (about 200°C or 400°F).

    About 10 min

  6. 6

    Carefully place the salt-crusted fish directly on the hot grill grates. Close the lid.

    About 1 min

    Cook’s note: Use a fish grilling basket if you have one to prevent sticking and make flipping easier.

  7. 7

    Grill for 10-12 minutes per side, or until the salt crust is firm and lightly browned, and the fish is cooked through.

    About 24 min

    Cook’s note: The internal temperature of the thickest part of the fish should reach 63°C (145°F).

  8. 8

    Remove the fish from the grill and let it rest for a few minutes.

    About 1 min

  9. 9

    Gently crack open the salt crust and peel it away to reveal the tender, cooked fish inside. Discard the crust and the aromatics.

    About 1 min

    Cook’s note: The skin will likely come off with the salt crust, leaving you with clean, flaky flesh.

  10. 10

    Serve the fish immediately with sticky rice and a spicy dipping sauce.

Keep it good

Storage

Store any leftover cooked fish in an airtight container in the refrigerator.

Reheating

Gently reheat in a microwave or oven until just warmed through to avoid drying out the fish.
