How to cook pasta
Fill a pot with 1 litre of water per each 100 grams of pasta. Do not add the pasta yet. Bring water to a fast boil, put in the pasta and add a pinch of salt. Stir occasionally, when cooking time reported in the package is due, drain the pasta and add to the sauce. Broadly speaking for each 100 grams of pasta you will need 1 litre of water and a teaspoon of salt.
