3Add a few glugs of passata di pomodoro and simmer vigorously to reduce.
4Add dry spaghetti and top it with about a cup of broth made with tomato paste and water.
5Let the strands sit in the bubbling liquid to absorb it and soften.
6Add more broth each time the pan threatens to dry out.
7Keep adding broth, turning the spaghetti over and reducing the sauce until the strands are cooked through.
8Increase the heat so the pasta at the bottom of the pan crisps, caramelizes, and scorches.
9Pull the spaghetti from the stove, twirl it onto a plate, and adorn the deliciously, deeply satisfying tangle with a drizzle of your very best extra virgin olive oil.
