1. Marinate the Fish

In a mixing bowl, combine 1 cup of grated coconut, 2 tablespoons of mustard paste, finely chopped green chilies, 1 tablespoon of ginger-garlic paste, 1 teaspoon of turmeric powder, salt to taste, and 2 tablespoons of mustard oil. Mix well until all ingredients are combined. Coat the Bhetki fish fillets thoroughly with this mixture and let them marinate for 30 minutes to enhance the flavors.

2. Prepare the Banana Leaves

If using banana leaves, briefly wilt them over an open flame or immerse them in hot water until they become pliable. This step makes it easier to wrap the fish securely.

3. Wrap the Fish

Take each marinated fish fillet and place it on a piece of prepared banana leaf. Fold the leaves over to create secure packets that will hold in moisture during cooking.

4. Cook

Steam the packets in a steamer for about 20 minutes until the fish is cooked through and flaky. Alternatively, you can place them on a plate inside a large pot filled with some water at the bottom; cover tightly and steam as well.

5. Serve

Once cooked, carefully unwrap the packets to reveal your beautifully steamed Bhetki fish. Transfer to serving plates and garnish with fresh coriander leaves for an aromatic finish. Serve hot alongside steamed rice for a complete meal!
