Hairy Bikers' Mama's curry

Heat a frying pan and add the ghee or oil. Brown the meat until sealed on all sides, then take it out of the pan and set aside.

Add the onion and garlic to the pan and fry until soft but not browned. Add all the spices and fry for 1 minute, no longer.

Put the beef back in the pan with the tomatoes and bring to the boil. Take the pan off the heat and stir in the yoghurt and vinegar, then season with the salt and sugar. Place back on the heat, bring back to the boil and simmer for at least 1½ hours until the meat is tender.
