Bengali Mustard Fish Recipes

Steps:

• In a bowl, marinate the fish in 1/4 tsp turmeric and a good pinch of salt, tossing to coat, then set aside. Using a spice grinder or a pestle and mortar, grind the mustard seeds to a fine powder. Put the tomato, garlic, 2 or 3 green chillies, the powdered mustard seeds, 1/2 tsp turmeric, a pinch of salt and 150ml water in the small bowl of a food processor and blitz to a smooth paste.
• Heat 3 tbsp of the mustard oil in a medium-sized non-stick pan until smoking, then take off the heat and wait for 30 secs. Add the nigella seeds to the pan and allow to sizzle for 10 secs, then add the paste. Cook over a medium heat, stirring occasionally, until all the excess liquid has evaporated and the paste releases its oil. Lower the heat and continue cooking for another 4 mins or so, until it darkens a little. Add 400ml water and the remaining chillies, bring to a boil and simmer for 7-8 mins until it has a medium consistency, not too watery. Check the seasoning and keep on a low heat while you fry the fish.
• Heat the remaining oil in a frying pan until smoking. Add the fish and fry on all sides for around 6 mins until golden brown. Add the fish to the mustard sauce, bring back to the boil and cook for 2 mins. Sprinkle on the coriander leaves and serve with rice, if you like.

Steps:

• Cut the fish into pieces that are about 2" x 1" and rub them evenly with the salt, turmeric, and cayenne. Cover and set aside in the refrigerator for 30 minutes-10 hours. Put the mustard powder, cayenne, turmeric, and salt in a small bowl. Add 1 tablespoon water and mix thoroughly. Add another 7 tablespoons water and mix. Set aside.
• Pour the oil into a medium frying pan and set over medium-high heat. When hot, put in the mustard seeds. As soon as they start to pop, a matter of seconds, add the cumin and fennel seeds. Stir once and quickly pour in the mustard paste. Add the green chilies, stir, and bring to a gentle simmer. Place the fish pieces in the sauce in a single layer. Simmer gently for about 5 minutes, or until the fish is just cooked through, spooning the sauce over the fish all the time.
