This is a very popular Bengali dish cooked on special festivals and occasions...
In this dish the mutton has to be well marinated. While cooking the mutton is sautéed well that is called Koshano in Bengali and hence the name Khosha Mangsho... Since the mutton is marinated well, the mutton cooks in its own juices, so no water is added while cooking. Usually it is slow cooked in a pot, but due to time constraint, I have cooked it in a pressure cooker.
