The Bronx Cocktail is essentially a perfect martini with orange juice added. It was ranked number three in "The World's 10 Most Famous Cocktails in 1934", making it a very popular rival to the Martini (#1) and the Manhattan (#2). Today, it remains a popular choice in some markets, and is designated as an Official Cocktail by the International Bartender Association.
