Method
- 1
Prepare the guanciale
Cut the guanciale into batons about 1cm thick. Put them in a cold, wide pan, then set it over medium-low heat. Cook for 8–10 minutes, turning occasionally, until the fat is translucent and the edges are crisp. Do not add oil.

Build the tomato sauce
Lift the crisp guanciale from the pan and reserve it. Leave about 3 tablespoons of rendered fat in the pan. Crush the peeled tomatoes by hand, add them with the peperoncino, and simmer gently for 10–12 minutes.

Cook the bucatini
Bring a large pot of water to the boil and salt it lightly—the guanciale and Pecorino are already salty. Cook the bucatini until 2 minutes short of al dente. Reserve at least 250ml of pasta water before draining.

Finish in the pan
Transfer the bucatini directly into the tomato sauce. Add a splash of pasta water and toss over medium heat for 1–2 minutes, until the sauce clings to every strand. Fold in most of the guanciale.

Add the Pecorino
Take the pan off the heat. Wait 20 seconds, then toss with half the Pecorino and another spoonful of pasta water if needed. This keeps the cheese creamy rather than clumpy.

Serve immediately
Divide between warm bowls. Finish with the remaining guanciale and Pecorino. The sauce should be glossy and savoury, never heavy or watery.
