Kosha Mangsho is a mutton curry made in Bengal. The dish comes from British times in Calcutta. The mutton (goat or lamb) curry is mixed with vegetables.

The mutton is slow cooked or pressure cooked and then put into a gravy of onions, tomato and spices. It’s typically eaten over rice.

The British version was served with dinner rolls. And was called Railway Mutton Curry. Because it was what was catered for long train journeys.

It’s typically eaten during Kali Puja, but Nobo Borsho is nearer. So eat it now.
