Kosha Mangsho | A labour of love

Kosha Mangsho again! Chunks of goat meat slow-cooked in a rich gravy with whole spices to a dark and soft texture that falls off the bones and melts in your mouth is indeed a labour of love. A finger-licking delicious mutton curry from the state of West Bengal that the world now relishes in so many versions. 

A few weeks ago I was in a phase, cooking off Bengali cuisine because I finally got my hands on a small cute bottle of mustard oil. Mustard oil in bong food is like coconut oil in Malabar food, it is best not to be replaced. That said, I am guilty of using other than mustard oil in all my previous preparations of bong food in this blog and trust me it does make a huge difference! 

Kosha Mangsho  | A labour of love

I already have a Kosha Mangsho recipe on the blog and so I planned to recreate my recipe with mustard oil. Before I began the preparation, I was just curious to know how the Bong Eats team made them. There are very few cooking Youtubers who mesmerize me. After my bong bestie shares any recipe, I go check Bong Eats video to get a hang of the process because ingredients can differ but the techniques matter. It is true, recipe sharing is a skill not everyone can do it. 

Did you notice the post title? Kosha Mangsho, a labour of love. It took me 3 hours to make it with the new lessons I picked from her video. I wanted to try again to see if I can make any quicker if I use a pressure cooker. Honestly, it did not really help with saving much time so I would stick to using cast iron kadai or stainless steel pot. That said, if the goat meat requires long cooking time then feel free pressure cook the marinated mixture, else, you can begin with tempering in a thick bottom kadai.

A labour of love is when you do something out of love for it and so you don't really expect anything in return. The three odd hours of slow cooking the mutton does need your attention every 10 minutes so it is not shut and cook and serve... you will truly be amazed at the transformation of the mutton meat to a dark shad that has dropped off the bones and simply melt in your mouth! And if you nailed it, then trust me, appreciations will start to pour!

Watching F eat Kosha Mangsho which I served with little rice and a couple of chapatis was a delight. The man of few words took the effort to say that he loved this. Hence, I decided to give this recipe another space in this blog.
