To begin making Bengali Bhetki Macher Paturi Recipe (Barramundi Fish Wrapped in Banana Leaf), mix the fish pieces with half teaspoon turmeric powder and salt in a bowl.
In a mixer grinder, make a paste of mustard seeds, poppy seeds and green chilies by adding a little bit of water.
Take the grated coconut in a bowl. Add mustard seeds paste, a bit of salt to taste and remaining turmeric powder. Mix and make a fine mixture with a fork.
Cover and keep them in the fridge for an hour.
Remove the fish from the fridge and mix with a teaspoon of mustard oil.
Stir gently, warm the banana leaves over an open flame for 30 seconds, make sure it does not get burnt.
Put banana leave pieces glossy side up over a plate, rub a little mustard oil on it. Now spread a teaspoon of marinated paste in the center of the banana leaf, place one piece of fish on the paste and put another teaspoon of paste on the top of fish piece so as to cover the fish piece by the paste from both sides then place a green chilli on top of it.
Fold the banana leaf to make it a square parcel and tie with thread that the parcels will not open while cooking. Repeat the process for all the fish pieces.
