Black-eyed Susan is a cocktail without a set recipe. In its basic form, it combines vodka and orange juice, but other ingredients can vary. The cocktail was created for Preakness Stakes, the annual horse race held at Pimlico Race Course in Baltimore, Maryland.
Along with vodka and orange juice, the cocktail usually includes pineapple juice, triple sec, and rum, while some versions also include peach schnapps or replace the rum with bourbon. Sour mix is also commonly added. The first recipe dates from 1973.
