For this dish you can use any fish. I used Seer Fish its called as Tengeri in Singapore. Pomfret will be best for this recipe.
-3 cloves of garlic
-one inch ginger
-1 table spoon oil
-1/4 spoon tamarind paste
-one spoon chili powder
-1/4 turmeric powder
-1/4 jeera powder
-1/4 coriander powder
-Fry onion, ginger, garlic till light brown and blend it in the mixer along with rest of the ingredients and make a fine paste.
-Marinate the fish in this masala and keep aside for 2 hrs.
-Wrap the fish with banana leaf (tie it or clip it with tooth pick) Shallow fry on a non stick pan and keep the pan covered.
The fish will be ready in 7 to 8 minutes.
(Optional: u can use desi ghee (clarified butter instead of oil)
