As you may know, the term lettuce comes from Latin "lacto", which indicates something made of milk: the motif can be traced in the presence of significant concentrations of latex within the plant as it did at the time of the ancient Romans. Today, Lactuca Sativa's cultivars, the most common widespread lettuce, including the oldest ones, such as the Trocadero, have a significantly reduced amount of latex, in some cases virtually absent, so the etymology of the word is definitely blurred. Nevertheless, from the earliest cultivations dating back to 5,000 years B.C. - lettuce is among the oldest crops in the West - today lettuce, in its many varieties and declinations, has always been part of the gastronomic traditions and peasants of the Mediterranean Basin, and in Central-Southern Italy found systematic and widespread use, as well as being an indispensable element of the Mediterranean diet and some local kitchens, especially Roman and Campania. The commercially available lettuce comes exclusively from field crops in Campania.
