In a large sauce pan add 1 litre of salted water for every 100g of pasta. For 250g of pasta add 2.5 litres of water
Bring the water to a gentle boil and put in the Tagliatelle
Cook for 3 – 4 minutes depending on preference
Gently heat the bolognese sauce in a frying pan without burning and transfer the Tagliatelle using a slotted spoon making sure that some of the starchy pasta waster makes into the pan with the tomato sauce. (The starchy pasta water is part of the dish.) You can always add 1 tablespoon of pasta water after if you would like.
Gently coat the Tagliatelle with the tomato sauce, plate and garnish with Parmesan
