Instructions Heat a heavy saucepan over a medium flame and then add the pancetta. Cook until it turns light pink, about two minutes. Add the olive oil and butter. Stir until the butter has melted. Add the onion, carrot, and celery. Cook gently until the onion is translucent, about ten minutes.Add the beef and salt. Turn up the heat and cook until the meat is lightly browned. Add the wine and the tomatoes. Bring to the boil and then cover the pan and turn the heat right down. Cook for one hour and forty-five minutes, adding a small amount of beef stock occasionally if the sauce gets too dry. Add the milk, stir through, and cook for a further fifteen minutes. Check seasoning and add salt if necessary. Serve with fresh tagliatelle. If you are making lasagna add single cream too. Like this:Like Loading...
