Shorshe baata diye maach bhapa (steamed fish in a mustard gravy)

This is one of the most famous delicacies in Bengal. While it is more popular with Hilsa fish or Ilish maach, and enjoyed on a rainy afternoon, it can be prepared using other fish as well. Here I include the recipe using Basa fish, which might not taste as good as Hilsa, but is a blessing for those who cannot stand the fishy smell.

All you need:

• Basa fillet - 1
• Mustard seeds - 3 tsp
• Turmeric powder - 1 tsp
• Salt - 1 and a half tsp or to taste
• Green chilies - 2 or to taste
   
  
• Mustard oil - 4 tsp
• Water - about 2.75 cups

Ready to cook?

1. Clean the fish thoroughly with water, and pat dry
       
   
2. Cut the fillet into medium sized pieces, on an average yields 10 pieces
     
   
3. Add half the salt and half the turmeric powder to the pieces of fish
4. Mix well, and let it set for 5 minutes
    
   
5. Grind the mustard seeds, the green chilies, and the remaining turmeric powder with a little bit of water to make a thick paste
    
   
6. Add the above paste to the mixture of fish, along with the remaining salt and 2 tsp of mustard oil, and mix well. Let it stand for 5 minutes
    
   
7. In a metal box that has a lid, pour the mixture of fish and spread it even
8. Sprinkle 2 tsp of mustard oil on the mixture (do not mix it)
9. Add about half a cup of water (depending on how runny you want the gravy to be, adjust the volume of water)
    
   
10. Close the box tightly with its lid
11. In a pressure cooker, place the grid that comes with the cooker
12. Add 2 cups of water
     
    
13. Place the box containing the fish evenly on the grid, ensuring that the grid contains the box. This is to make sure the box does not float on the water
     
    
14. Cover the pressure cooker and place it on high flame
15. After the first whistle, simmer the cooker for 7 minutes (if you use Hilsa, it could take up to 10 minutes)
16. Switch of the gas and let the cooker cool down of its own accord
17. Carefully open the box, and check if the fish has cooked properly, if it has not, you might have to return it to the pressure cooker and simmer for another couple of minutes
18. Serve hot with rice or khichudi (another Bengali delicacy)
