Limoncello
Limoncello (Italian pronunciation: [limonˈtʃɛl:o]) is an Italian lemon liqueur mainly produced in Southern Italy, especially in the region around the Gulf of Naples, the Sorrentine Peninsula and the coast of Amalfi, and islands of Procida, Ischia, and Capri. It is also produced in Abruzzo, Basilicata, Apulia, Sicily, Sardinia, Menton in France, and the Maltese island of Gozo. Although there is debate about the exact origin of the drink, it is at least one hundred years old.
Production
Traditionally, it is made from the zest of Femminello St. Teresa lemons, also known as Sorrento or Sfusato lemons. Lemon zest, or peels without the pith, is steeped in rectified spirit until the oil is released. The resulting yellow liquid is then mixed with simple syrup. Varying the sugar-to-water ratio and the temperature affects the clarity, viscosity, and flavor. Opaque limoncellos are the result of spontaneous emulsification (otherwise known as the ouzo effect) of the sugar syrup and extracted lemon oils.
