Norcia, Valnerina, Umbria — the Norcia pork tradition is documented from Roman times. Norcia was a medieval centre of the pork trade and the norcino guild was among the most powerful in central Italy. The IGP protection for Prosciutto di Norcia was granted in 1997.
Norcino (a pork butcher from Norcia) is so synonymous with pork expertise that the Italian word 'norcineria' means a specialist pork butchery, and 'norcino' denotes mastery of the art. Norcia's pork tradition rests on the ancient practice of raising Cinta Senese and local large white pigs in the oak forest floors of the Valnerina, where they forage on acorns and roots in autumn. The key preparations are: prosciutto di Norcia IGP (rubbed with a garlic-rosemary-salt-pepper blend and aged minimum 12 months), capocollo (neck muscle rolled and cured), lonza (loin cured with black pepper and white wine), and corallina sausage (finely ground pork with coriander and black pepper). The norcino also handles the black truffle — the two are inseparable in Umbrian cuisine.
Prosciutto di Norcia sliced thin has a deeper, more assertive flavour than San Daniele or Parma — the garlic and rosemary cure leaves a faint herbal note; the mountain air aging develops a slightly more intense, almost gamey sweetness. The fat is white and slightly firm. With Umbrian schiacciata and a glass of Sagrantino, it is the best introduction to the Valnerina.
The Norcia technique: cold ambient temperature during processing (winter curing, from November through February, timed to the 'ammazzata del maiale' — the pig slaughter). All cuts rubbed with natural salting mixtures — specific to each cut (prosciutto gets the garlic-rosemary-pepper cure; capocollo gets wine-and-spice; salsiccia gets only salt, pepper, wild fennel, and peperoncino). Aging in natural mountain air at altitude — the Norcia valley's dry, cold, slightly acidic mountain air is considered ideal. Minimum aging: prosciutto di Norcia IGP requires 12 months; some producers age to 24 months for the stagionato.
The black truffle connection: norcini in Norcia are also the primary dealers in Umbrian black truffle (Tuber melanosporum). The combination of cured pork fat and black truffle is one of Umbria's great pairings — a thin slice of lonza with black truffle shaved over toasted pane di Altamura is one of the preparations that justifies the Norcia pilgrimage. The corallina sausage (a fine-ground sausage with coriander seed) is Norcia's most characterful fresh sausage and is specific to the town.
Curing at wrong temperature — warm-weather curing promotes putrefaction; the norcino tradition is specifically winter-based for a reason. Under-salting — insufficient salt allows bacteria to penetrate the muscle; over-salting produces a product that is unpleasant. Under-aging — the prosciutto di Norcia's flavour develops in the second half of aging; short-aging produces a flat product.
