Step 2
- a.Shallow Fry the Fish
- b.Heat mustard oil in a wide pan or kadai over medium-high heat. Wait until the oil is very hot and you see faint smoke rising; this reduces its pungency.
- c.Carefully place the marinated fish pieces into the hot oil, ensuring not to overcrowd the pan.
- d.Fry for 2-3 minutes on each side until they turn a light golden brown. The goal is to firm up the fish, not to cook it through.
- e.Once fried, remove the fish with a slotted spoon and set aside on a plate.

Step 3

- b.In the same pan with the remaining oil, lower the heat to medium.
- c.Add the panch phoron and allow the seeds to crackle and release their aroma, which should take about 30 seconds.
- d.Add the slit green chilies and sauté for another 15-20 seconds.
- e.Pour in the tomato puree. Add the remaining 0.5 tsp turmeric powder and 1 tsp salt.
- f.Cook the mixture for 5-7 minutes, stirring occasionally, until it thickens and you see oil separating from the sides of the masala.

Step 4
- a.Simmer the Curry
- b.Pour 2.5 cups of warm water into the pan and stir to combine with the tomato base. Bring the gravy to a rolling boil.
- c.Once boiling, gently slide the fried fish pieces into the gravy.
- d.Reduce the heat to a low simmer, cover the pan with a lid, and let it cook for 5-6 minutes. This allows the fish to absorb the tangy flavors of the curry.

Step 5
- a.Finish and Garnish
- b.Turn off the heat completely.
- c.Gently stir in the Kazi Nemu or lime juice. Adding it off the heat preserves its fresh flavor and prevents bitterness.

- e.Let the curry rest for at least 5 minutes before serving. This helps the flavors to meld beautifully. Serve hot with steamed rice.
What to keep in mind.
5 tips from the recipe — small details that make a real difference to the final dish.
- 1For the most authentic flavor, use mustard oil and heat it until it's lightly smoking before adding any ingredients. This tempers its pungent flavor.
- 2Frying the fish lightly before adding it to the curry is a crucial step to prevent it from breaking apart while simmering.
- 3Always add lime juice (Kazi Nemu) after turning off the heat to retain its fresh aroma and avoid making the curry bitter.
- 4Use ripe, red tomatoes for a naturally sweet, tangy flavor and a vibrant color in your curry.
- 5Do not overcook the fish. A few minutes of frying and a few minutes of simmering are all it needs to be tender and flaky.
Adapt it for your goals.
