Corn ‘n’ Oil is a cocktail made with a combination of aged blackstrap rum and falernum (a sweet, tropical syrup). In order to prepare it, both ingredients should be poured into a tall glass over ice, then stirred. There are many variations of this drink, so lime juice or Angostura bitters are sometimes also added to the combination.
The drink is typically garnished with a lime slice or lime zest twist. It is quite popular in Barbados and Jamaica, although its origins are unknown. The American version is prepared with more rum, while the Caribbean versions are prepared with larger amounts of falernum.
