Limoncello is a traditional Italian liqueur made from lemon zest, alcohol, sugar, and water. It originates from the southern regions of Italy, particularly Campania, Sorrento, and the Amalfi Coast. The bright yellow drink is known for its sweet and tangy flavor, making it a popular after-dinner digestif. To make limoncello, the lemon peels are steeped in high-proof alcohol for several days, allowing the oils to infuse. Afterward, a simple syrup of sugar and water is added, resulting in a refreshing beverage that is often served chilled. It can also be used in cocktails or as a flavoring in desserts.
