Spaghetti Sauce Recipe(From Nerone, Italy)

In a large saucepan, add some extra virgin olive oil on a low to medium heat. When warmed, add the chopped bacon and cook until very well done. Next, add the carrots and tomato paste and stir frequently. You will have a very thick preparation, but keep going. Add the bay leaf, onion and crushed rosemary and stir frequently. Now add the chopped celery and continue to cook, stirring frequently. When thoroughly warmed, add the Pomi tomatoes and the basil leaves because you will need the moisture content to start the melding of these ingredients. Lower the heat and cover.
