The name of this dish comes from Persian: "Rogan" means clarified butter and "Josh" means intense heat. Together it suggests “cooked in oil at intense heat”. The unique use of fennel and dry ginger sets it apart from other curries. It is traditionally cooked using the "dum pukht" method, which is slow cooking in a sealed pot. This allowed the mutton to become buttery soft and infused with spice. It's often part of the Kashmiri wazwan, a royal multi-course meal.
