For egg tagliatelle, make a well with the flour and semolina, adding all ingredients and mixing until well combined. Rest for 1 hr. Roll with pasta machine to 1mm thickness in several batches, if necessary. Each batch must be dusted with flour and cut into 15cm-wide strips to be readied for insertion into pasta machine for cutting into tagliatelle. Prepare salted boiling water for cooking tagliatelle for approximately 1 min, being careful not to overcook.
Spread mince over bench and dust lightly with 1 tbsp of flour. Fry beef mince in a very hot pan with olive oil until lightly brown.
Fry finely chopped onion, carrot and celery on medium heat. Soak porcini mushrooms in warm water for at least 10 mins.
Add the finely diced pancetta to the pot and fry on a low heat for 5 mins. Strain mushrooms and chop roughly and add to mince with sangiovese and cook till wine evaporates. Add beef stock, tomato purée, tomato paste and bay leaf to mince and season to taste. Place lid on pot and simmer for 1½ hrs, stirring occasionally.
