Clean the fish and cut into pieces if required.

Grind the ingredients: grated coconut, turmeric powder, chilly powder, ginger, garlic, shallots with little water to a smooth paste.

Add this paste, salt, cocum pieces, big onion and green chillies to fish with sufficient water.

Put pot onto the stove and slow the flame when it boils.

Put another pan on stove and pour oil. Heat oil and splutter the mustard seeds, fry curry leaves and pour seasoning into the fish curry. Tips: Instead of kudampuli, can use mango, chemmen puli, tomato & ambazhanga.
