This is one of the traditional recipes of Bengali cuisine.
I usually make it somewhat differently.. but this is something I tried after reading various recipes over the web.
Ingredients:
- 8 pieces of Hilsa
- 2 - 3 green chillies
- I medium onion sliced and fried till brown.
- 1/2 cup yellow and black mustard seeds
- 1/4 tsp of turmeric
- 1/2 cup grated coconut
- 2tbsp mustard oil
- Corrainder leaves for garnishing
- salt to taste
Method
- Soak the black and yellow mustard seeds for about half an hour in hot water. This makes the seed soft and easy to grind.
- Grind the soaked mustard seeds with salt, green chillies and coconut till you have a paste.
- Take a big bowl and smear the paste on the fish with your hands.
- Add the fish to two bowls and lay them flat.
- Spread half of the fried onions on top on each bowl.
- Add 1 tbsp each mustard oil to the bowls of fishes over the paste.
- Finely chop corriander leaves over it and cover the bowls and add to a water bath or a pressure cooker one on top of the other and steam it for 20 minutes. You can steam the bowls separately as well. ( you can steam all in one bowl if you have a big pressure cooker.. )
- If the paste is too dry, sprinkle some water before steaming so that you can have little gravy.
- Serve with hot rice.
PS: I liked adding coconut to the paste. It gives a nice light flavor along with the mustard.
