Put the onion, tomato, coconut, ginger, garlic, chilipowder, all the Tita Goan Fish Masala and the tamarind juice into your food processor and grind well to make a smooth paste (masala).
Heat a deep pan on a medium flame, add the oil and heat.
Add the masala paste you just ground to the oil and fry for 5 minutes.
Now add the 2 cups of water (add more water if you would like more gravy) and salt to taste and bring the gravy to a boil. Reduce the flame to a simmer and cook for 10 minutes.
Add salt to taste.
Gently add the pieces of fish to the gravy and cook for 15 more minutes. Do not cover the pan.
Garnish with fresh coriander leaves.
Serve with Basmati rice and any of the vegetable dishes you can find on our website.
