Combine basil, olive oil, salt, and pepper in a food processor and process until smooth.
Bring 5 quarts of water to a simmer and remove from heat.
In a large mixing bowl, break apart the curd into small pieces (it is best to use your hands). Season the curd with kosher salt.
Carefully pour the hot water over the curd. Using 2 long wooden spoons, carefully but quickly begin working the curd, forming it into a smooth, lumpless ball. Once curd is of smooth texture, remove from water and place onto a plastic film lined sheet pan.
Evenly stretch the mozzarella on the sheet pan to cover the entire surface. Spread a thin layer of the basil puree on the mozzarella. Place a thin layer of the prosciutto di Parma over the basil puree. Using the underlying film, begin rolling the mozzarella tightly, forming a pinwheel.
Wrap the entire log of mozzarella in plastic wrap and place into refrigerator. Allow to rest for 8 to 24 hours.
Slice the mozzarella log into 1-inch pieces. Dredge in flour, then in egg wash and then lightly coat with bread crumbs. Reserve in refrigerator until time to pan fry.
Pan fry in oil until golden brown on both sides.
