Instructions
  1. At first, clean and wash the Katla fish pieces properly under running water. Spread (1/2) teaspoon of salt and (1/2) teaspoon of turmeric powder over them and marinate well. Cover the container and keep the fish aside until you are done with rest of the preparation.
  2. Add a little water to the plain yogurt and beat it well with the help of a spoon. It should turn slightly thinner and there should be no lump in it.
  3. Chop up 1 onion finely and keep it in a bowl. Make small pieces of the other onion, put them inside a blender and prepare a smooth paste.
  4. Make small pieces of the ginger and blend them just like the previous way to come up with a paste.
  5. Cut the green chilies into two halves vertically. If you wish, you can discard the seeds. The number of green chili may vary depending upon your taste.
  6. Chop the fresh coriander leaves finely by discarding the stalk and keep them aside. You will need this at the time of garnishing.
  7. Now, take a wide shallow frying pan and pour the mustard oil into it. Turn on the flame and allow the oil to heat up. Once it becomes smoking hot, add the marinated fish pieces to it and fry both sides lightly. Make sure that the fish pieces are not over-fried. Just cook until they turn light golden brown, remove them from the oil and keep aside.
  8. Add cinnamon sticks and cardamoms to the remaining oil. Wait 2-3 seconds to let them release the beautiful smell and then, add the bay leaves. Stir fry for a few seconds.
  9. Add chopped onion to the frying pan and sauté for a couple of minutes. Once the onions become translucent, put the cumin powder, red chili powder and ginger paste to it. Stir fry for next 2 minutes.
  10. Add the onion paste to the pan. Also, put the remaining salt, turmeric powder and sugar in it. Sauté for 2 to 3 minutes so that the entire thing becomes light brown.
  11. Now, pour the beaten yogurt as well as the tomato ketchup into the pan and stir well. Keep the heat medium and wait until the oil is released. After 4-5 minutes, add water to it and mix everything together.
  12. The gravy mixture will start to boil within 5-6 minutes. Then, add the fried fish pieces to it, cover the pan with its lid and let the whole thing get cooked for next 5 minutes. Keep the flame low during this time.
  13. Finally, transfer the fish pieces to a nice serving dish along with the gravy and garnish with chopped coriander leaves.
