One from bartender Joe Scialom (1942) calls for brandy and gin, while another from Tiki pioneer Victor J. Bergeron (AKA Trader Vic) primarily uses rum along with "secret ingredients" and is known for being garnished with a cucumber.
[1][4] Bartender Joe Scialom was looking to make a hangover drink for allied troops and according to the story made one as a "cure" for the suffering soldiers who complained about the poor quality of liquor in the area.
Bourbon was frequently swapped out for the brandy where it was available however, and for a short period of time the drink was also called the suffering bar steward, for those that found the use of the word bastard offensive.
Other Vic recipes called for the use of his commercial Mai-Tai mix[12] as a basis along with multiple rums, lime juice, and the unusual garnishment for a Tiki drink of a cucumber peel.
[13] A hand written note allegedly from a waiter at Trader Vic's circa 1970 listed the "key" ingredient as being the inclusion of rum from Barbados.
