Minced Beef Pie

Preheat the oven to 200C/400F/Gas 6.

Heat the oil in a deep frying pan and fry the beef mince for 4-5 minutes, breaking it up with a wooden spoon as it browns.

Add the onion and cook for 2-3 minutes, then stir in the tomato purée and cook for 2-3 more minutes. Stir in the flour and cook for a further minute, then add the chopped mushrooms, the stout or beef stock and a couple of dashes of Worcestershire sauce. Bring to the boil, then reduce the heat, cover the pan with a lid and leave to simmer for 20 minutes. Set aside and leave to cool, then turn the meat mixture into a one litre pie dish.
