Step 1
- a.Prepare Seeds and Banana Leaves (15 minutes)
- b.In a small bowl, combine the black mustard seeds, yellow mustard seeds, and poppy seeds. Cover with warm water and let them soak for at least 15 minutes. This softens them for easier grinding and reduces bitterness.
- c.While the seeds are soaking, wash the banana leaves thoroughly. Carefully pass each leaf over a low open flame for about 10-15 seconds on each side. This makes them pliable and prevents them from tearing when you fold the parcels.

Step 2
- a.Create the Mustard Marinade (5 minutes)
- b.Drain the soaked seeds completely. Transfer them to a grinder or blender jar.
- c.Add the grated coconut, 4 green chillies, turmeric powder, salt, and 3 tablespoons of water to the jar.
- d.Grind everything into a smooth, thick paste. Scrape down the sides as needed. Be careful not to over-grind, as this can make the mustard bitter.
- e.Transfer the paste to a mixing bowl. Stir in the whisked curd and 4 tablespoons of mustard oil until well combined.

Step 3
- a.Marinate and Wrap the Fish (5 minutes)
- b.Gently pat the fish fillets dry with a paper towel. Add them to the bowl with the marinade and coat each piece generously on all sides.
- c.Lay a softened banana leaf on a clean, flat surface with the shiny side facing up.
- d.Place one marinated fish fillet in the center of the leaf. Top it with an extra spoonful of the marinade and one slit green chili.
- e.Fold the banana leaf neatly from all four sides to create a secure rectangular parcel. Tie it with a piece of cotton kitchen thread to hold it together.

Step 4
- a.Cook the Parcels (15 minutes)
- b.Choose your cooking method: Steaming (recommended) or Pan-Frying.
- c.For Steaming: Arrange the parcels in a steamer basket over boiling water. Cover and steam for 12-15 minutes on medium heat, until the fish is cooked through and flakes easily.
- d.For Pan-Frying: Heat 1 tablespoon of mustard oil in a non-stick pan over low-medium heat. Place the parcels in the pan, cover with a lid, and cook for 7-8 minutes on each side. The leaf will become charred, which adds a lovely smoky flavor.

Step 5
- a.Serve Hot

- c.Serve the Patot Diya Maas immediately, allowing each person to unwrap their own parcel. It pairs perfectly with hot steamed rice.
What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1For the most authentic flavor, use fresh, high-quality mustard oil. Its pungent aroma is key to this dish.
- 2Do not skip soaking the mustard seeds. It's a crucial step to reduce their inherent bitterness.
- 3If you don't have a gas stove to soften the banana leaves, you can briefly dip them in hot water to make them pliable.
- 4Ensure your marinade paste is thick. A runny paste will leak out of the parcels during cooking.
- 5For a deeper flavor, you can let the fish marinate for up to 30 minutes before wrapping.
- 6Tie the parcels securely but not too tightly, as the fish will expand slightly while cooking.
