Don’t settle for green, white and red, or names that end in A, I or O. Look for “Made in Italy” on the package, the region it’s from, or a DOP or IGP certification. And watch out for products that say generic things like “packed in Italy” because often enough these products have been packaged in Italy, but other than that have nothing to do with Italy.
DOP stands for Denominazione di Origine Protetta (or, Protected Designation of Origin). A European Union certification, it guarantees a product was made by local farmers and artisans in a specific region or area, using traditional methods.
IGP stands for Indicazione Geografica Protetta (or, Indication of Geographical Protection). And it traces food specialities back to their geographical origin to at least one phase in production, but not to all phases, like DOP.
