Limoncello

Limoncello is an Italian lemon liqueur mainly produced in southern Italy, especially in the region around the Gulf of Naples, the Amalfi Coast and Sicily. It is the second-most popular liqueur in Italy and is traditionally served chilled as an after-dinner digestif. It is also a popular homemade liqueur, with various recipes available online and in print. Limoncello is made from the zest of lemons and usually has a slightly turbid appearance, which originates from the presence of small essential oil droplets suspended in the drink. The exact origin of limoncello is disputed. The industry trade group Federazione Italiana Industriali Produttori Esportatori ed Importatori di Vini, Acquaviti, Liquori, Sciroppi, Aceti ed affini says that limoncello was created at the beginning of the 1900s by the grandmother of Maria Antonia Farace, who lived in a small guesthouse in Isola Azzurra. US sources[who?] say that it was either invented in Sicily about 100 years ago, or that it was first made on the Amalfi Coast, where several villages and islands claim to be its place of origin. Journalist Kristen Tillotson reports that it may either have been invented by a citrus-grove tender from Azzurra around 1900 or by monks or fishermen much earlier.
