Keep aside. Heat 3 tsp oil in a non-stick skillet.

Add mustard seeds and cumin seeds in the oil. When it starts to sputter, add the fenugreek seeds; once you get a sweet and sour flavour and the seeds turn golden brown, add curry leaves and onion.

Add a pinch of salt so that the onion gets cooked quickly. When onion turns golden brown, add tomato and cook for another 2-3 minutes.

Add cumin powder, coriander powder and turmeric powder, cook for a minute. Add the mixture of tamarind juice,leave it for a couple of minutes till the sauce is well cooked.

(You should not get any smell of tamarind once properly cooked).Add a pinch of sugar while the sauce is simmering.

Add fish at the end, cook for another 10 minutes in medium flame. Serve hot with rice.
