This is Bolognese sauce as they make it in Bologna. Only tomato purée is used, never tomatoes.
For the Sauce:1 tbsp olive oil 3 rashers of streaky 'pancetta' bacon, chopped 1 large onions, chopped 2 garlic cloves, crushed 1 carrot, chopped 1 stick of celery 500g lean minced beef 1 large glass of red wine 1x400g can tomato puree 2 fresh or dried bay leaves salt and freshly ground black pepper
For the Pasta:400g-500g/14oz - 1.1lb dried tagliatelle freshly grated parmesan cheese, to serve
To make the Sauce:
1. Heat the oil in a large, heavy-based saucepan and fry the bacon until golden over a medium heat. Add the onions and garlic, frying until softened. Increase the heat and add the minced beef. Fry it until it has browned. Pour in the wine and boil until it has reduced in volume by about a third. Reduce the temperature and stir in the tomato puree, celery and carrots.
2. Cover with a lid and simmer over a gentle heat for 1-1½ hours until it's rich and thickened, stirring occasionally.
3. Cook the tagliatelle in plenty of boiling salted water. Drain and divide between plates. Sprinkle a little parmesan over the pasta before adding a good ladleful of the sauce. Finish with a further scattering of cheese and a twist of black pepper.
