A cocktail made with equal parts of gin and orange juice is known as an orange blossom or an Adirondack. This drink is also traditionally made with equal parts of gin, orange juice and sweet vermouth. The classic cocktail originated in the 1920s during the Prohibition era.
To make an orange blossom, combine the ingredients in a cocktail shaker filled with ice. Shake the contents, and strain into a chilled cocktail or martini glass. Garnish with an orange wheel or wedge. Alternatively, serve this drink as a gin 'n' juice by pouring it into a Collins glass filled with ice.
