Shake ∙ 3 min ∙ 24.2% ABV ∙
The Knickerbocker is a rum sour built with light gold rum, orange curaçao, raspberry syrup, and lime juice, served over crushed ice. Tart and lightly sweet with a soft berry finish, the crushed ice keeps every sip cold, diluted, and refreshingly slushy to the last drop.

- Strain into the glass 2/3 filled with cubed ice

Tips
- Shake hard and fast — the small amount of curaçao and syrup need real agitation to fold evenly into the rum and lime.
- Cut the lime shell garnish cleanly so it sits flat on the crushed ice instead of sliding into the glass.
History
The Knickerbocker is one of the oldest documented American cocktails, first printed in Jerry Thomas's 1862 The Bar-Tender's Guide as a rum drink built with lime or lemon, raspberry syrup, and curaçao. William Terrington's 1869 Cooling Cups and Dainty Drinks reprinted a nearly identical version alongside a very different sherry-and-seltzer "Knickerbocker à la Madame," and Harry Johnson's 1882 New and Improved Bartender's Manual kept the rum-and-raspberry formula but added pineapple and orange. All of these early versions were served over shaved ice.
Who actually created the drink, and where, has never been established; sources agree only that the name points to New York. "Knickerbocker" was a nickname for the descendants of the city's original Dutch settlers, popularized by Washington Irving's 1809 satirical A History of New York, written under the pen name Diedrich Knickerbocker, and the word became a byword for anything New York. The famed Knickerbocker Hotel, sometimes wrongly credited as its birthplace, was not built until 1906, decades after the drink was already in print, so the connection is coincidental at best.
The cocktail continued to evolve into the 20th century: Harry Craddock's 1930 Savoy Cocktail Book listed a "Knicker-Bocker Cocktail," an unrelated gin martini with sweet and dry vermouth, alongside a "Knicker-Bocker Special" that was served straight up and closely resembled the earlier rum-and-raspberry recipes rather than the ice-filled originals.
