Ilish Paturi: Bengali New Year Special

Ingredients
Ilish/Hilsa fish- 4-6 pieces
Mustard paste
(I mixed yellow and black mustard seeds in 2:1 ratio. Yellow mustard is for flavor, black mustard is for punch. Soak in water first, then strain and make a paste. I used Magic Bullet for making the paste)
Green chilies paste and slit whole for garnish
1 tsp yogurt
Grated Coconut
Turmeric powder
Mustard oil
Salt to taste

Method

1. Clean the fish. Smear the pieces with turmeric powder, salt, mustard paste, mustard oil, coconut and green chili paste. 
2. Cut the banana leaves into rectangles. Wrap each fish in a separate packet, add a slit green chili on top, tie with kitchen string.
3. Heat mustard oil in a tawa or  frying pan. Fry the packets covered to cook uniformly. Turn every 5 mins till done. I cooked for 15-20 mins.
4. Serve with steamed white rice.
