Before you start making Goan Fish Curry, keep all the ingredients ready. Start with washing and cleaning the fish well. Cut the fish into 6 pieces. Now roast coriander seeds, whole red chilies and cumin seeds in a pan. In a blender, add the grated coconut, garlic and ginger paste and malt vinegar along with the roasted spices. Blend all these into a smooth paste.
Now in a cooking pan, heat some oil. Add the chopped onions and fry till light brown. Now add the chopped tomatoes and the slit green chilies and fry for 3-4 minutes. Keep stirring constantly to avoid it from getting sticking. Once it is fried, add the ground paste and then add 1 ½ cup of water. Boil the Goan fish curry for a few minutes and then add salt according to your taste. Cover it with a lid till the fish cooks in the gravy.
Since the Goan fish curry is hot and sour, it goes well with hot steamed rice. Being a spicy dish, rice is a better option and it can be served for lunch or dinner. Other than Pomfret fish, any other one-bone fish can also be used for Goan fish curry as every fish has its own taste.
