What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Grind the soaked mustard with very little water; a thin paste can make the gravy sharp rather than creamy.
- 2If your grinder heats up, pulse in short bursts so the mustard paste stays smooth and less bitter.
- 3Smoke the mustard oil lightly before frying the fish to tame its raw pungency without losing its signature flavor.
- 4Only sear the fish briefly; over-frying now will make it dry and more likely to break while simmering.
- 5Keep the flame low once the mustard paste goes into the pan, because high heat can turn mustard bitter.
- 6Rest the curry for 5 minutes before serving so the mustard, chili, and fish flavors settle into the gravy.
- 7This tastes even better with steamed rice after a short rest, but reheat very gently so the fish pieces stay intact.
Adapt it for your goals.
Steamed
Skip the pan-frying and steam the fish in the mustard paste mixture for a softer, more delicate bhapa-style result.
low oilLow-oil
Reduce the oil slightly and poach the fish directly in the mustard gravy; good if you want a lighter everyday version.
prawnPrawn
Use large prawns instead of fish steaks for a quicker mustard seafood curry with the same bold Bengali flavor.
milderMilder
Cut down the green chilies and use more yellow mustard than black for a softer heat and less assertive bitterness.
