What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Bring the whisked yogurt to room temperature before adding it, or the gravy is more likely to split.
- 2Smoke the mustard oil first, then lower the heat; this softens its raw pungency without losing its Bengali character.
- 3Only sear the fish briefly in step 2 so it stays intact and finishes cooking gently in the yogurt gravy.
- 4Cook the onion paste until the raw smell disappears and it turns light golden, or the curry can taste harsh and muddy.
- 5Add the yogurt little by little while stirring constantly on low heat for the smoothest, silkiest sauce.
- 6Use warm water, not cold, when thinning the gravy so the yogurt emulsion stays stable.
- 7Let the curry rest for a couple of minutes after the garam masala goes in; the fish firms up slightly and the gravy tastes rounder.
Adapt it for your goals.
Low-oil
Shallow-sear the fish in less mustard oil and use a nonstick pan; you still get the mustard aroma with a lighter finish.
bonelessBoneless
Use firm boneless fillets for easier serving, especially for children or guests who prefer not to deal with fish bones.
spicierSpicier
Add an extra slit green chili or a little more red chili powder for a sharper heat that still fits the yogurt-based gravy.
hilsa styleHilsa-style
Make it with hilsa if available for a richer, more traditional Bengali character, adjusting handling gently because the fish is delicate.

Frequently asked questions
