Water, sugar, pure alcohol and lemons, macerate the lot and a few months you'll have home-made to be served cold in little ceramic glasses. Italians traditionally make their own liqueurs. For this purpose, supermarkets sell bottles of pure alcohol of close to 100 percent proof. Don't be surprised if you come limoncino, limonetta or other liquore di limone during your trip. Limoncello is a protected designation of origin and must be produced from Sorrente (Campania) lemons to benefit from the name.
