There are some differences between the two types of meat, and they primarily affect the taste. Prosciutto is a dry-cured salted Italian ham that is typically sliced thin, and it has a salty taste. Prosciuttini is different because it looks more like a polished ham that is typically covered in black pepper to provide its unique flavor.
Prosciutto is also made from the meat of the pork legs. It is prepared by covering the meat with salt, and then it is left to rest. During that time, the salt draws out the blood and all the moisture, and that’s important because the process prevents bacteria from entering the meat. The salting also helps to give the meat more flavor.
Prosciuttini is found in many delis and Italian specialty shops. Although it is made similarly to prosciutto, its claim to fame is that it’s a ham that’s made from pork using black pepper and other spices. So it is a spicier version of Prosciutto.
