The Blue bird is a gin or vodkacocktail with blue curacao. The Savoy Cocktail Book gives the recipe as gin with Angostura bitters and curacao.[1] Another recipe from the Café Royal Cocktail Book (1937) uses vodka instead of gin, adding maraschino liquor, and fresh lemon juice. The original gin-based cocktail was reimagined by Bill Tarling, who was known for various blue colored cocktails. The earlier recipe used angostura bitters which would have effected the final color of the cocktail, and may be the reason behind Tarling's changes to the original recipe.[2]
The bluebird is shaken with ice and served in a chilled cocktail glass with an orange peel garnish.[3]
