Bengali Fish Curry

My friend Sushama is married to a Bengali and she dishes out the most delicious Bengali preparations. 

½ kilo surmai or any other fleshy fish cut into pieces.

Ginger 1” piece

½ pod garlic, peeled

1 tablespoon mustard seeds

1 tsp jeera

1 small onion chopped

Lightly fry fish pieces, drain and keep aside. Fry chopped onion in 1 tablespoon oil. Add 2 cups water, salt to taste and fish and bring to the boil. When the fish is cooked, add all the other ingredients ground fine, wait till it comes to the boil and switch off flame.
