How to make:
DRY SHAKE (without ice) all ingredients to emulsify. Add ice, SHAKE again and fine strain into chilled glass.
Even Mr Embury would approve of this version. Overproof Jamaican rum and copious amounts of bitters make this drink.
Adapted from David A. Embury's 1948 'Fine Art of Mixing Drinks', where he writes, "This cocktail is supposed to have been a speciality of the elder Morgan of the House of Morgan, which goes to prove as a bartender he was an excellent banker."
