Serves 4–6
1½ tablespoons olive oil
1kg lean diced beef (such as chuck, blade or gravy beef)
2 onions, diced
2 cloves garlic, crushed
350g mushrooms, sliced
2 tablespoons tomato paste
2 cups beef stock or water
1 teaspoon salt
3 teaspoons Worcestershire sauce
3 teaspoons cornflour mixed to a paste with 2 tablespoons cold water
3 tablespoons sour cream
Heat the oil in a saucepan over medium–high heat and sauté the beef until well coloured. Add the onion, garlic and mushrooms and cook for 3 minutes more. Stir in the rest of the ingredients, except the cornflour paste and sour cream.
Bring to the boil, then place a lid on the pan and reduce to heat low. Simmer for 2 hours or until the meat is tender.
Remove the lid and thicken by stirring in some or all of the cornflour paste. Allow to cook for 5 minutes more, remove from heat and mix in the sour cream. Season with salt and pepper to taste.
