What is this discoloured patch in my smoked prosciutto? I bought an Italian selection of cooked meats from a well-known British supermarket chain, which begins with T and rhymes with Fresco.

Within this selection is smoked prosciutto. However, it appears to contain discoloured patches which range from light brown to black, and I’m unsure as to whether to be concerned.

My initial thought was that it may be peppercorns but, on closer inspection, it doesn’t appear to be, and I’m unsure as to whether to return the product to the store.
It looks like lard to me. The cut side of a ham is covered with lard to prevent drying out when curing, often mixed with spices. I wouldn't worry about it. Smoked cured ham is called speck in Italian, and mainly produced in the north, notably in Alto Adige.
