Step 2
- a.Fry the Fish
- b.Heat the mustard oil in a kadai or heavy-bottomed pan over medium-high heat. Wait until it becomes pale yellow and just starts to smoke lightly; this step is crucial to mellow its pungency.
- c.Carefully slide the marinated fish into the hot oil. Be extremely cautious as they tend to splatter. Use a splatter guard or partially cover the pan.
- d.Shallow-fry for 3-4 minutes per side until they are golden brown and crisp. Fry in batches if necessary to avoid overcrowding.
- e.Once fried, remove the fish with a slotted spoon and set them aside on a plate.

Step 3
- a.Temper the Spices
- b.In the same oil, lower the heat to medium. Add the nigella seeds and let them sizzle for about 20-30 seconds.
- c.Add the slit green chilies and the ginger paste. Sauté for about 1 minute until the raw aroma of the ginger disappears.

Step 4
- a.Prepare the Gravy
- b.In a small bowl, create a smooth paste by mixing the remaining 1/2 teaspoon of turmeric powder, red chili powder, and cumin powder with 2-3 tablespoons of water.
- c.Add this spice paste to the pan. Stir and cook for 2-3 minutes on low-medium heat until the spices are fragrant and you see oil separating at the edges of the masala.
- d.Pour in 1 cup of warm water and add the remaining 1/2 teaspoon of salt. Stir well and bring the gravy to a vigorous boil.

Step 5
- a.Simmer and Finish
- b.Gently slide the fried fish pieces back into the boiling gravy.
- c.Reduce the heat to low, cover the pan, and let it simmer for 5-7 minutes. This allows the fish to soften and absorb the rich flavors of the gravy.
- d.Uncover the pan. The gravy should have thickened and be clinging to the fish. If it's too thin, simmer for another 2 minutes without the lid.
- e.Turn off the heat. Let the curry rest for at least 10 minutes before serving to allow the flavors to meld.
