To begin making the Parshe Macher Jhal Recipe, firstly marinate the fish with turmeric powder and salt. Keep it aside for 5 minutes.
Next, heat mustard oil in frying pan and fry the fish till it turns light brown on both the sides. Keep the fish aside.
Reheat the same oil, add the kalonji seeds and green chillies. When the seeds start to crackle, add the tomato puree, remaining turmeric powder, red chilli powder and salt.
Cook on a moderate flame till oil has been released from the masala paste.
At this stage, add about 1-1/2 cups of warm water, give it a nice stir and bring the curry to a boil.
Adjust the salt, add the fried fish, mustard paste and cook for a further 3 to 4 minutes. Add the coriander leaves and serve hot.
Serve Parshe Macher Jhal along with Steamed Rice and Bengali Style Cholar Dal for your weekday meal.
