Heat 1 tsp of the oil in a large saucepan over a high heat. Add the mince, season and cook until browned, breaking it up with a wooden spoon as it cooks. Remove from the pan, discarding all the fat, and set aside.
Heat the remaining oil and cook the onion, garlic and ginger with some seasoning for 8 mins until soft. Add the curry powder, potato and carrots, and cook for a few mins more. Stir in the tomato purée, 500ml water or vegetable stock, and the beef. Cook on a medium heat for 20 mins or until the potatoes are tender. Serve with basmati rice, fresh coriander, and mango or lime chutney.
