Averna is a popular Italian bitter digestif that was named after its inventor Salvatore Averna who created it in 1868. Some sources state that the recipe was handed to the Avernas by a monk of the local San Spirito monastery. The exact ingredient list remains the Averna family secret, but this bittersweet liqueur is said to be made with more than 60 different herbs, roots, pomegranate, and the essential oils of bitter Sicilian lemons.
