How to Make It
Heat the olive oil in a medium enameled cast-iron casserole. Prick the sausages several times with a fork and brown them in the casserole over moderately high heat. Transfer the sausages to a plate and set aside.
Add the pancetta to the casserole and cook until most of the fat has been rendered, 3 to 4 minutes. Add the onion and carrot and cook until lightly browned, about 5 minutes. Add the garlic, cinnamon, cloves and bay leaf and cook until the garlic is beginning to color. Add the wine and simmer until almost evaporated, about 5 minutes.
Return the sausages to the casserole. Add the broth and tomatoes and bring to a boil; the liquid should almost cover the sausages. Reduce the heat to low and simmer the sausages, turning them several times, until they are tender, about 35 minutes. Remove the sausages, cover with foil and set aside for later use. Skim the sauce; if it seems very brothy, boil it down for about 5 minutes. Discard the cinnamon stick and bay leaf. Add the parsley and rosemary and season with salt and pepper.
In a large pot of boiling salted water, cook the pasta just until al dente. Drain well and transfer to a serving bowl. Add 1/2 cup of the grated cheese and toss briefly. Add the sauce and toss again. Pass the remaining cheese at the table.
