Fiocco di prosciutto comes from the pork thigh used to produce the famous Culatello di Zibello.
The pork comes from Italian farms of the controlled supply chain for the production of Prosciutto DOP.
Culatello comes from one side, and from the other side comes the Fiocco di Rifilato, which is massaged and salted, then tied and aged in the same humid cellars where the Culatello is aged.
