What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Pat the surmai steaks completely dry before adding to the gravy to prevent excess wateriness.
- 2If fresh coconut is unavailable, use frozen grated coconut; avoid desiccated coconut as it lacks creaminess.
- 3Let the curry rest off heat for 5 minutes after cooking — this lets the fish absorb the tangy gravy without overcooking.
- 4Taste the tamarind water before adding; adjust quantity if your tamarind is unusually sour or mild.
- 5Fenugreek seeds turn bitter quickly — pull them out the moment they change color during tempering.
- 6Use a wide, shallow pan so the fish steaks sit in a single layer and cook evenly without breaking.
Adapt it for your goals.
Low-oil
Reduce coconut oil to 1 teaspoon and dry-roast the mustard seeds, cumin, and fenugreek before grinding with the coconut paste — cuts calories without losing aroma.
prawn alternativePrawn alternative
Swap surmai for large raw prawns (shell-on) and reduce simmering time to 3-4 minutes after adding them — prawns cook much faster than fish steaks.
coconut milk shortcutCoconut-milk shortcut
Replace freshly grated coconut with 1 cup thick canned coconut milk — skip the grinding step and add it at the end for a quicker, equally creamy curry.
mango kokum variationMango-kokum variation
Replace tamarind with 2 pieces of dried kokum (soaked for 15 minutes) for a fruitier, milder sourness typical of Goan Catholic curries.
