The freshest and most delicate sheep cheese is primo sale (or sometimes primosale). It’s named after its first salting, and is sometimes flavoured with peppercorns, olives, chili flakes, walnuts, pistachios or almonds.
A company is Sicily also makes a primo sale di bufala using fresh buffalo milk from Campania.
Secondo sale is pretty much a young, half matured, pecorino aged for at least four months. A nice one is nero siciliano secondo sale, massaged with ground black pepper and olive oil to give it a distinctive black rind.
