Prosciutto and Jamón Serrano are not the same - even if they look so much alike.  What makes the two looking very similar is the fact that both come from white pigs. Therefore, they have the same look when sliced. However, once you taste each dry-cured meat, you will begin to understand where the similarities end. Jamón Serrano is saltier and with stronger scent and flavor as compared to Italian prosciutto.
