Clean fish pieces and pat dry using a kitchen towel. Based on the kind of fish, cut the pieces accordingly. Make shallow cut marks on both sides of fish.
Mix / grind the ingredients listed under marination. Add curry leaves as it is.
Marinate fish with the masala and curry leaves. Keep it aside for 30 minutes.
Heat oil in a flat pan. Shallow fry the fish pieces for 3 minutes on both sides or until done. Fry it over medium flame. Serve it with onion rings and lemon.
Notes
Score the fish well, so the marinade can penetrate deeply and flavor it evenly.
Pat the fish dry before marinating to help the spices stick better.
You can use lemon juice or vinegar in the marinade for a mild tang and to help tenderize the fish.
For extra crispness, add a small amount of rice flour or cornflour to the marinade. Use just enough to coat the fish lightly.
