Let's remember above all that the Bronx cocktail is a tradition and a legend to be respected: a Bronx is made with squeezed orange juice!
The Bronx was most likely created by Johnnie Solon, a famous bartender who arrived at the Waldorf Astoria hotel in New York in 1899. It was within a few years of his arrival at the hotel that Johnnie Solon would have created the Bronx.
Historian Albert S. Crockett published "TheOld Waldorf-Astoria Bar Book" in 1934 in which he tells the story of the creation of the Bronx. One day when Johnnie Solon was making a cocktail named "Duplex" for a client, his butler named "Traverson" arrived offering to create a new cocktail and telling him that a client had felt that he (Johnnie ) could not. Johnnie would then have made a cocktail that came from a sudden idea: mix 2 thirds of gin for 1 third of orange juice, then finish with 2 equal doses of white and red vermouth. Johnnie then allegedly poured his new recipe into a cocktail glass and handed it to Traverson who then drank the glass in one gulp.
The Bronx is a neighborhood in New York, but the name of the cocktail wouldn't come from here. Johnnie Solon reportedly saw strange and unfamiliar beasts at the zoo, something some of his customers had already noticed who had previously drunk too many cocktails. When Traverson asked Johnnie what name he wanted to give to his cocktail, it was by remembering this story of strange beasts that he named his cocktail the "Bronx".
The cocktail party was immediately a success, the hotel liquidated one to several cases of oranges to be squeezed per day.
