Let’s talk about the difference between Parma Ham and prosciutto. Parma Ham is the more well-known and less formal way to say Prosciutto di Parma. Prosciutto, though, is made in many areas of Italy and would be named something different. The Parma Ham process is similar in these other areas of Italy, but are named locally, like Prosciutto di Modena or Prosciutto di San Daniele.
