Bhetki Macher Paturi Bhetki Fish Banana Leaf

Barramundi (bhetki) fillets marinated in mustard paste with poppy seeds and cooked in banana leaf — the premium fish version of the paturi preparation. Bhetki is the prized white-fleshed river and coastal fish of Bengal, far less bony than hilsa.

Ingredients

4 bhetki (barramundi/Asian seabass) fillets about 150g each
banana leaves — 4 large pieces
For the paste:
3 tbsp yellow mustard seeds — soaked 20 minutes
1 tbsp white poppy seeds — soaked 20 minutes
3 green chilli
1/2 tsp turmeric, salt
2 tbsp raw mustard oil + 1 tbsp for drizzling
1/2 tsp nigella seeds (kalonji) for flavour

Method

Make the mustard-poppy paste: Drain soaked mustard and poppy seeds. Grind together with green chilli, turmeric and salt. Add 3 tbsp water. Grind 4 minutes to a very smooth, silky paste. Mix in 2 tbsp raw mustard oil and nigella seeds.
Marinate the bhetki: Coat each bhetki fillet generously with the mustard-poppy paste on all sides. Rest 20 minutes — the thick fleshed bhetki needs more marinating time than hilsa which is thinner.
Prepare banana leaves: Soften by briefly passing over a flame. The leaves should be pliable and lightly charred on the edges.
Wrap each fillet: Place one marinated fillet on each leaf. Drizzle 1/4 tsp more raw mustard oil over each. Wrap securely. Toothpick the seal.
Heat a flat griddle: Heat a cast iron griddle or flat heavy pan on medium heat.
Cook on the griddle: Place the sealed parcels on the griddle. Cook 7 to 8 minutes on the first side — the leaf will char and darken significantly.
Flip: Flip carefully. Cook 7 to 8 minutes on the second side.
Test: Open one parcel — the bhetki should be fully cooked and opaque white throughout. It should flake easily when pressed.
Serve in the leaf: Serve the sealed parcels at the table. Open theatrically.
Eat with steamed rice: Scoop the mustard paste from inside the charred leaf over steamed rice alongside the fish.
Note: Bhetki (barramundi/Asian seabass) is one of the most prized fish of Bengal — preferred by many over hilsa for its lack of fine bones and its firm, white, delicately flavoured flesh. The bhetki paturi is made for special occasions and family celebrations as a premium alternative to the hilsa paturi. In Kolkata fish markets, bhetki commands a premium price and is specifically sought out for this style of preparation.
