Rogan josh is another all time favourite on the curry house menu. It was originally a Kashmiri dish but is equally at home in the Punjab. An authentic rogan josh will be made with lamb and may, at its most elaborate, contain dozens of spices. The Kashmiri and Punjabi versions do differ (the Kashmiri does not traditionally contain onions or garlic) but they are both highly spiced and share a deep red colour derived from the liberal use of dried red Kashmiri chillies. The curry house rogan is also red but the colour comes from red peppers and tomatoes rather than Kashmiri chillies. The restaurant rogan is characterised by its garnish of tomato pieces and fresh coriander. It is usually medium hot.
