Cut the meet into 3cm strips and coat a casserole dish with cooking oil spray or use a teaspoon of vegetable oil. Brown the meat in batches and put to one side. Cook the onion, garlic, and spices in the same casserole dish, stirring until the onion is soft whilst ensuring that the spice doesn´t stick or burn. Return the meat to the dish and add the stock and water and bring to the boil.
