Take 4 pomfret fish in a plate. Wash and clean them thoroughly. Use a knife and make cuts on both sides of the fish. Apply 1 tbsp ginger-garlic-chili paste, 2 tsp lemon juice and ½ tsp salt. Let them mar-inate for 15 min.
In grinder jar, add 1 cup grated fresh coconut, ½ cup coriander leaves, and 8-10 green chilies. Then, add 15 garlic cloves, ginger 1 inch piece, and add 2-3 tbsp water. Make a smooth paste of it. The paste will get a nice green color due to the coriander leaves and green chili.
Heat 4 tbsp oil in a kadai on medium flame. Once oil is hot, add green paste in kadai.
Let the green paste cook for 8-10 min. Keep stirring in between. Add ½ tsp cumin powder, ½ tsp garam masala, and 2 tsp lemon juice. Mix everything well. Let the masala paste cool down.
Once the masala paste is cooled down, divide it equally for 4 pomfrets. Stuff green masala paste inside the slits of the fish on both sides. Also, stuff it inside the fish. Repeat the same process for the remaining pomfrets.
On a plate, take 2 tbsp rava, 4 tbsp rice flower, ¼ tsp salt and ¼ tsp of red chili powder. Mix well together.
Coat all the stuffed fish well with rava mixture. Heat enough oil in a kadai on a medium-high flame for 5 min.
Gently drop the fish in hot oil and turn the flame to medium. Fry 7-8 min for one side. Turn the fish to the other side and let it fry for 7-8 min. Fry one pomfret at a time, so it can cook properly.
Serve hot on a plate with onion rings and lemon wedges.
