What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Pat the fish steaks completely dry before marinating to ensure the paste adheres well and the fish fries crispy.
- 2Do not marinate longer than 30 minutes, as the mustard paste can turn bitter and overpower the fish.
- 3Heat mustard oil until it smokes, then let it cool slightly before frying — this tames its raw pungency.
- 4Use a heavy-bottomed pan (like a tawa) for even heat distribution and a consistently golden crust.
- 5Dust off excess rice flour coating to prevent burnt spots in the pan and keep the crust clean.
- 6Fry the fish in a single layer without crowding; cook in batches if needed to maintain oil temperature.
- 7Serve immediately after frying — the crust stays crisp for only about 10 minutes off the heat.

Air-fried
Cook the marinated, rice-floured steaks in an air fryer at 200°C for 10–12 minutes, flipping halfway. Suitable for those who want a lighter, less oily version without losing crispiness.
pan seared with no rice flourPan-seared with no rice flour
Skip the rice flour and pan-sear the fish directly in mustard oil for a softer crust and a more intense, pure mustard-garlic taste. Ideal for those who prefer a less crunchy exterior.

Replace rohu with mackerel steaks. Mackerel's firmer, oilier flesh stands up well to the bold marinade and gives a richer, more robust flavor. Adjust cooking time by 1 minute per side.
