Railway Curry is traditionally made with lamb or mutton. If you want to use lamb or mutton then marinate as above and increase the cooking time. Cubed lamb would take around 60 - 90 minutes. On the bone or mutton a little longer. It can even be made with lamb shanks which would take around 3 hours. If using lamb or mutton then it would be best to cook in the oven in a covered pan. Put in the oven after the curry gravy is added. Cook at around 165°C in a conventional oven or around 20°C lower for fan assisted.
