Bring water to a boil in a steamer pot. Place the wrapped parcels on the steamer rack, cover tightly, and steam on medium heat for 18-20 minutes.

What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Soak the mustard seeds in warm water for the full 20 minutes to mellow their sharp bite and ensure a creamy paste.
- 2When softening banana leaves over the flame, stop as soon as they turn glossy—overheating makes them brittle.
- 3Blend the mustard-coconut paste to a smooth, thick consistency; add water sparingly, just enough to move the blades.
- 4Slit the fish steaks lightly before marinating so the paste penetrates deep into the flesh for maximum flavor.
- 5Tie the banana leaf parcels tightly with kitchen string to trap steam and prevent the marinade from leaking out.
- 6Keep the steaming water below the rack and top up with hot water halfway through to maintain a steady gentle steam.
