How to make Kosha Mangsho (Bengali mutton curry)?
This Bengali style mutton bhuna requires very basic ingredients that is easily present in your pantry. Authentic kosha mangsho (mutton curry) is made with mustard oil. But if it is unavailable you can use any veg oil or sunflower oil. Here are a few simple steps to make perfect Kosha Mangsho (bhuna mutton). It is a simple recipe but its best to start the preparation overnight.
Marination for Mutton kosha: It is an important step. The ingredients that go in this marination are yogurt, onion paste, ginger-garlic paste, raw papaya paste (or any meat tenderiser), chilli powder, turmeric powder, cumin powder, coriander powder, salt, and mustard oil. Now let’s get dirty and marinate the meat really nice with hands. It’s so therapeutic. It’s best to marinate the goat meat or lamb meat overnight or at least 4-5 hours.
Look at that juicy marinated meat. It already smells so so good.
Oh! look at my hand model!! It is my father pouring mustard oil in the marinade. Did I ever mention he is such an amazing cook. Infact this is how he makes kosha mangsho. And it is finger licking good.
For the Mutton curry:
The mustard oil is tempered with whole spices like cinnamon, cardamon, cloves and bay leaves and dried chillis. Then thinly sliced onions are added and fried until golden brown. Then marinated meat is added and then slow cooked fo almost 1 to 1 1/2 hours until the meat is cooked through, soft, tender and juicy.
Finally right at the end of the cooking a dollop of ghee and gorom moshala (Bengali garam masala powder) is added. I add my homemade desi ghee. Here is the recipe of my homemade ghee. Bengali garam masala is made with spices like cinnamon, cardamom and cloves. I like to freshly pound my garam masala in my pestle and motor right before adding in my curry.
Another ingredient that I like to add in this Bengali style mutton curry is potatoes. But it is completely optional or its a personal preference. I like big pieces of potatoes in my curry because it soaks up the all the lovely flavours and juices from curry and oh boy! it is just so delicious.
I love to serve Kosha Mangsho with hot puris, pulao, parathas or with hot steaming rice.
