Fun fact: the guy who created AA, Bill Wilson, said this was the first alcoholic drink he ever had. Bill Wilson later on took a bunch of psychedelic drugs, met “God”, who told him he needed to stop drinking. The other members who helped form AA with him convinced him to keep the God part of the program but that he should drop the doing psychedelic drug part of the rehab. The Bronx was invented by Hugo Ensslin in the 1910s and printed in his book, Recipes for Mixed Drinks, which was the last cocktail book to come out before prohibition in the United States. The Waldorf-Astoria later printed an altered version of the drink that was much stronger than the original. A quick Google search of the Bronx cocktail will 9 times out of 10 return the original Hugo Ensslin recipe.
