Tradition's Southside Recipe

We'd drink this refreshing classic cocktail all afternoon—it's easy to make and easy to gulp. Gin, mint, and citrus are an unbeatable combination, with a little soda to lighten it up. At Tradition in San Francisco, Ian Scalzo and his bartending team serve it in a mason jar with a fragrant mint sprig.

Note: To make simple syrup, combine 1 cup water with 1 cup sugar in a small saucepan and heat over medium heat, stirring constantly, until sugar is dissolved. Cool before using. Simple syrup will keep in a sealed container in the refrigerator for up to 5 days.
