It is ideal when served with rice, bread or boiled tapioca.
Clean the fish well . Grind coconut well with red chilli powder and turmeric. Mix the fish with the ground masala, cocum, salt and sufficient water. Cook well in medium heat. When the gravy thickens add oil and crushed onions and curry leaves. Remove from fire and serve hot.
The same can be made with coconut milk instead of ground coconut. Strain first milk (1/2 cup) and second milk (2 cups) from the grated coconut by adding water. Saute crushed onions, ginger (1 small piece), turmeric, red chilly powder in oil (or you can mix all the ingredients in the second milk and bring to a boil) Add the second milk, fish, salt and cocum. Boil on medium heat. When the fish is almost done and the gravy thickens add the first milk and remove from fire.
Tips :Instead of cocum raw mango pieces are used.
