The Gin and Tonic is a classic cocktail made by mixing gin with tonic water, typically served over ice. It is often garnished with a slice of lime or lemon, which adds a refreshing citrus flavor. The drink is known for its crisp and slightly bitter taste, making it a popular choice for many. Originating in the 19th century, the Gin and Tonic became popular among British soldiers in tropical regions as a way to consume quinine, a treatment for malaria found in tonic water. Today, it remains a favorite drink worldwide, enjoyed for its simplicity and refreshing qualities.
