Place the whole dried peperoncino and the olive oil together in a cold wide pan. Set over a medium-low flame. Do not rush this stage. The oil must come up to heat with the chilli inside it, extracting the fat-soluble capsaicin and colouring the oil a deep amber-red. The process is complete when the peperoncino skin blisters and the oil takes on a vivid rust colour and a sharp, hot scent fills the kitchen.

Add the crushed garlic to the coloured oil only once the peperoncino is sizzling. Cook until the garlic turns pale gold at its edges. Garlic burns faster than chilli and must receive less heat exposure; remove it at this point if it threatens to colour beyond pale gold.

Add the hand-crushed San Marzano tomatoes directly into the pan. The texture must be uneven — irregular pieces of flesh, not a smooth purée. Raise the heat to establish a vigorous simmer immediately. This is where the dish lives or dies: the sauce must cook at a rolling, active simmer for exactly 15 to 20 minutes. Longer cooking sweetens and mellows the peperoncino; shorter cooking leaves the tomato raw. At 15 to 20 minutes the sauce is vivid, slightly loose, and retains the full, sharp violence of the chilli. The surface should sputter and the colour remain a bright, unmuddied red.

Bring a large pot of generously salted water to a full rolling boil. Cook the mezze maniche or rigatoni until al dente according to the maker's timing, reserving one ladleful of the starchy cooking water before draining.

Add the reserved pasta cooking water to the sauce and stir to integrate. Add the drained pasta to the pan. Toss over the heat for one minute until every tube is coated and the sauce has entered the cavities. The finished surface should be glossy and the sauce should cling, not pool.

Remove the peperoncino from the pan. Remove the pan from the heat. Add the chopped flat-leaf parsley and toss once. Serve immediately with Pecorino Romano grated at table. The parsley should smell fresh and green against the heat.
