Kosha mangsho

Kosha Mangsho is an almost dry spicy mutton curry cooked the Bengali Way. Almost all Bengalis have grown up licking their fingers to Kosha Mangsho’s velvety gravy and biting into the juicy pieces of the meat. All families have their secret Kosha Mangsho recipe and each one is unique in a way but every dish tastes heavenly. Here is my version of this dish, which I have discovered accidentally. When I was cooking a mutton preparation, my pressure cooker didnot whistle properly and I end up with succulent pieces of soft mutton wrapped up in a spicy gravy.
