Porchetta umbra is the inland sandwich built from the Norcia reading of the roast, and what defines it against the Lazio and Tuscan styles is the pairing of strong wild fennel with assertive black pepper as the two leading notes together. This is the porchetta of the norcini, the pork butchers of Norcia, who roll a boned pig with garlic, a heavy dose of finocchietto, black pepper used with a firm hand, and salt, the rosemary kept minor. The profile is green and bitter from the fennel, sharp from the pepper, leaner and more aromatic than the fattier Castelli cut, the meat moist and the skin a hard crackling. It is carved onto a sturdy Umbrian country loaf with nothing added, the bread chosen as a plain frame for a roast that is already loud.
The work was done at the spit, hours before any panino was built. The roll is seasoned through its depth so the fennel and pepper reach the centre and every slice tastes complete rather than only the surface, and it is roasted slowly so the fat renders soft while the skin sets into the shattering cotenna. For the sandwich the meat is taken with a strip of that crackling worked back into the slices, because the snap against the soft pig is the texture the build exists for. The bread is sturdy and close-crumbed, an Umbrian country loaf or an unsalted Tuscan-style bread that does not argue with the herb, and no sauce is added because a fennel-and-pepper roast is already whole. It is eaten warm or at room temperature so the fat stays soft and the wild fennel and pepper stay forward; cold dulls both.
Umbria and the Norcia tradition carry this one roast in several registers, and each is its own subject rather than a version of this one. There is the sagra van porchetta carved at the festival, the norcineria counter version sliced to order, the leaner loin-only build, and the hand that leans harder on pepper than fennel. Each is the same Umbrian fennel-and-pepper roast met by a different bread or balance, and each deserves its own article rather than being crowded in here.
