Finely mince the onion, carrot and celery and put them in a saucepan with liberal amounts of olive oil and a pinch of salt. Fry lightly for about 10-15 minutes until soft, stirring occasionally.

Add the minced meat and mix well with a wooden spoon, breaking up the meat. Fry until it browns a little, stirring every now and then.

When the meat is lightly browned, add the tomato paste and stir through. Add the wine and allow to simmer until the wine has softened the meat or evaporated.

Stir in the tomato puree, season with salt and pepper. Simmer very slowly in a covered saucepan over low heat, stirring occasionally. When the sauce starts to get dry, add some hot stock and continue simmering until the desired consistency is reached.

Cook the pasta in lots of boiling water, with a little salt, until the pasta floats to the top. Strain and serve with the ragù alla Bolognese and a handful of freshly grated Parmigiano Reggiano.
