Casarecce con Sugo di Salsiccia e Broccolo Rabe Campano — Cook

Ingredients

400 g casarecce, dried S-shaped twisted tubes
400 g salsiccia napoletana, fresh pork sausage with fennel seeds and chilli, casings removed
300 g cime di rapa (broccoli rabe / rapini), tender tops and small leaves only — thick stalks discarded
60 g Pecorino Romano, finely grated
3 tbsp extra-virgin olive oil, Campanian (Cilento or Irpinia DOP preferred); plus more at table
60 ml pasta cooking water, reserved just before draining (approximately 4 tablespoons)
1 tsp fine sea salt, for pasta water; adjust to taste

Method

1
Bring a large pot of well-salted water to a rolling boil. Working over the bowl, strip the cime di rapa of their tender tops and small leaves; discard all thick stalks. Drop the tops into the boiling water and blanch for 60 seconds. Lift out with a spider or slotted spoon and set aside — the blanching water remains in the pot for the pasta. The rapini should be vivid green and just wilted.
2
Heat the olive oil in a wide sauté pan over a medium-high flame. Crumble the salsiccia napoletana into the pan in coarse, irregular pieces. Cook without moving for 2–3 minutes, then turn and continue until the sausage is deeply caramelised on all sides and the fat has rendered freely. Remove the sausage pieces to a plate, leaving all rendered fat in the pan. The sausage must be browned, not merely cooked through — pale sausage lacks the flavour depth that caramelisation provides.
3
This is where the dish lives or dies: add the blanched rapini tops to the hot sausage fat in the pan over a medium flame and cook, turning frequently, until the leaves have absorbed the rendered fennel-pork fat and become glossy and tender — 3 to 4 minutes. The pan should smell of fennel and bitter grass simultaneously; that union is the structural flavour principle of this preparation. Return the caramelised sausage to the pan and stir to combine.
4
Cook the casarecce in the reserved blanching water until al dente according to the packet. Reserve 60 ml of the starchy cooking water, then drain the pasta. Add the pasta directly to the sauté pan along with the reserved cooking water. Toss over a low flame for 1–2 minutes until the pasta water, sausage fat, and rapini bitterness have formed a light emulsified coating that clings to the S-twist cavities of the casarecce — the sauce should not pool at the bottom of the pan.
5
Remove the pan from the heat. Add the finely grated Pecorino Romano and toss to incorporate. The residual heat melts the cheese into the sauce; added off heat, it retains its sharp, saline edge rather than turning stringy. Taste: the balance sought is bitter-sweet-fat in tension, with the Pecorino's salt as the resolution. Serve immediately with a thread of raw extra-virgin olive oil over each bowl.
