I was first served a similar dish by my friend Carlo at Galloni Prosciutto in Langhirano, near Parma. He took thin slices of prosciutto, stuffed them with Robiola, and tied them close with a chive. A mouthful of flavor. Here I cook them and use an aged cheese, which is more tasty than a fresh cheese. Cook the “purses” just long enough to brown them. Overcooking will make them salty, and since Prosciutto di Parma is an air-cured product, it doesn’t need to be cooked to be rendered edible. When buying the prosciutto, ask for slices from the widest part of the ham, measuring about 8x4 inches.
