Porchetta is a savory, fatty, and moist boneless pork roast of Italian culinary tradition. The carcass is deboned and spitted or roasted traditionally over wood for at least eight hours, fat and skin still on. In some traditions, porchetta is stuffed with liver and wild fennel, though many versions do not involve stuffing. Porchetta is usually heavily salted and can be stuffed with garlic, rosemary, fennel, or other herbs, often wild. Porchetta has been selected by the Italian Ministry of Agricultural, Food and Forestry Policy as a prodotto agroalimentare tradizionale (PAT), one of a list of traditional Italian foods held to have cultural relevance.
