Curated this. Difford's has the date wrong - the earliest reference I could find was the 1917 (2nd edition) of Hugo Ensslin's book. Updated link, made minor changes (no egg white, limes were smaller, added sugar) to conform to cited link. This drink is right in the middle of the Grenadine explosion in the mid 1910's, so I'd think that it was created to show off the bright red color of pomegranite grenadine. Thanks, Zachary
Usually this was called the Bacardi Cocktail even when it didn't contain Bacardi. It was 1936 that Bacardi won the court case to forbid a "Bacardi Cocktail" to use any other rum. Obviously, this Ensslin recipe pre-dates that lawsuit, but the Bacardi Cocktail published in 1913 pre-dates Ensslin so perhaps he was renaming it so as not to confuse the consumer. He had to know of it since it was rather popular back in the day.
