Refreshingly tart, this traditional limonata is made from Sicily's famed Siracusa lemons. While perfect on its own, this has become a favorite mixer of ours, especially for warm weather drinking. Mix it with gin and pour over ice for the world's easiest Collins, or with Cocchi Americano for a low-ABV cooler. For something more exotic, try it with bitter Italian liqueurs like Cappelletti and Cardamaro.
