The Whiskey Sour is of the older cocktail recipes. The cocktail recipe was originally seen in Jerry Thomas’ book, The Bartender’s Guide, in 1862. The history behind the conception of the drink; however, actually originates a century before that, when sailors and those looking for a new life in the new America’s would fix alcohol and their scurvy-fighting rations (think limes/lemons) as a more fun way to get their nutrients.  Once these sailors and immigrants would finally land (sometimes the trek being longer than a year) they would continue to drink their favorite way of getting their daily dose of vitamins.
