The Whiskey Sour was one of the vestiges of nineteenth-century mixology to survive Prohibition and experience broad popularity during the postwar period. This is my take on what a really good bourbon-based sour reflective of that period should be with the iconic orange-and-cherry garnish. If you make it with vanilla syrup, it’s got a really nice, subtle creamsicle flavor; egg white advised.

Whiskey Sours with egg white came into favor in the 1920s, almost certainly a product of the vibrant cocktail scene that flourished overseas during Prohibition. It has been called the Boston Sour by some, including, unsurprisingly, the Old Mr. Boston Official Bartender’s Guide, first published in the 1930s. The Rattlesnake, a Savoy Cocktail Book drink, is a Boston Sour with absinthe.

The Whiskey Sour with a red wine float (aka a “claret snap”) has gone by various names including the Continental Sour and Southern Sour and, though it likely originated in Chicago, people in 1880s Boston called it the “New-York Sour,” and the name has stuck. It can be served over a large ice cube or up in a chilled coupe; at Gigantic, we favor the former.

Though the Sour template predates the Fix slightly, the latter–a Sour served over crushed ice–was an incredibly popular member of the family in the mid-nineteenth century. Our recipe is diluted with a measure of water, just like the earliest extant Fix and Sour recipes–a nod to their evolution as a single-serving punch.
