Add the uncooked spaghetti to the pan and spread them out with a wooden spoon so they can absorb the flavors. Let them stick to the pan over medium heat.
As soon as they stick, flip them using tongs and start cooking by pouring ladles of boiling red broth. From this moment on, do not stir the spaghetti anymore.
After about 15 minutes,the Spaghetti all'Assassina are ready.
