"Kasha Mangsho" is a semi-dry slow-cooked goat meat preperation in bengali style. There is another type of goat meat recipe in bengali style which is just opposite to this, with a good amount of curry and with less "kasha" or frying the meat, which I posted earlier here, we call it "Pathar mangshor Jhol(Goat meat curry)"
