6-7 Bata fish, cleaned and washed
4 tbsp Mustard seeds (I used yellow seeds)
1 tbsp Vinegar
3-4 Green chilies
A pinch of Onion seeds
1/2 tsp Turmeric powder + a big pinch for marinating
2 tbsp grated Coconut (optional)
3 tbsp Mustard oil, strictly mustard oil as no other oil will do justice to this dish
Salt to taste
Soak mustard seeds and vinegar in a small bowl in warm water for half an hour. Grind the mustard with a green chili (or you can add according to your preference) and a pinch of salt at the time of grinding.
You may add 1-2 tsp water if the mixture is too dry while grinding. Now add 1/2 cup of water, salt and turmeric powder in it and keep aside Marinate fish pieces with some salt, turmeric and red chilly powder. Keep aside for 15 minutes.
Heat a part of mustard oil in a flat pan and fry fish pieces one at a time on low flame till light brown and keep aside.
Discard the oil in which you fried the fishes, heat fresh oil. Now add onion seeds and few green chilies into the hot oil and when the seeds splutters, add mustard paste.
Cover the pan for 2-3 minutes and then add fried fishes. Simmer for 3-4 minutes and turn off the flame.
For more pungent flavour you may add raw mustard oil over the final dish. Serve with plain rice.
