Lazio — Amatrice, Rieti province (historically disputed between Lazio and Abruzzo)
The canonical Amatriciana from Amatrice — using guanciale (cured jowl), Pecorino Romano, San Marzano tomato, white wine, and dried chilli on tonnarelli or spaghetti. The Amatriciana originale uses no onion (contentious but documented in Amatrice's municipal recipe), and guanciale must be cured with black pepper and not substituted with pancetta. The guanciale is rendered slowly until the fat is translucent and the meat bronzed but not crisp, then white wine deglazes the pan before the crushed tomatoes are added. Pecorino is added only at service, not cooked into the sauce.
Savoury guanciale fat with tomato sweetness and Pecorino's sharp, salty bite; the chilli provides warmth without heat — one of the world's great pasta sauces in four ingredients
{"Use only guanciale — not pancetta; the fat composition and curing flavour are fundamentally different","Render guanciale slowly (low heat) until the fat runs clear and the meat is lightly bronzed — crispy guanciale is wrong","Deglaze with dry white wine and let it evaporate completely before adding tomato — the wine must not be detectable in the finished sauce","Use San Marzano DOP tomatoes, hand-crushed — the texture should be chunky, not smooth","Pecorino Romano at service only — never added during cooking, which makes the sauce grainy"}
{"A tiny pinch of dried chilli flake (not Calabrian, but the milder Lazio variety) is traditional — heat should be background, not foreground","Cut guanciale into 1cm batons (not dice) — the shape provides the traditional presentation and the right ratio of fat-to-meat per bite","Reserve pasta cooking water to loosen the sauce at the moment of tossing — a tablespoon is usually sufficient","The pasta should be rigorously al dente — the sauce is not rich enough to tolerate soft, starchy pasta without losing definition"}
{"Substituting pancetta — fundamentally changes the dish's character and fat flavour profile","Adding onion — the municipal recipe of Amatrice does not include onion; adding it shifts the flavour profile toward a generic tomato sauce","Crisping the guanciale — Amatriciana guanciale should remain tender and silky, not crunchy","Using Parmigiano instead of Pecorino Romano — the sharpness and saltiness of Pecorino is the required contrast"}
