MADE IN THE USA. Each Del Duca® Prosciutto is prepared in the United States using the ancient European tradition of dry-curing, making for a truly mouth-watering experience. After applying sea salt, our Del Duca® Prosciuttos are aged for a minimum of nine months. Our experts inspect each Del Duca® Prosciutto individually to determine when they have reached perfection. The process is lengthy but it ensures that every slice has a consistently sweet – never salty – flavor.
