The Western Sour is a rye whiskey sour built with pink grapefruit and lime juice, falernum, and sugar syrup, shaken and served over crushed ice. Crushed ice keeps the finish crisp and cold, while a spiced sweetness lingers under a tangy, citrus-bright edge that never turns sharp.
The Western Sour is a tiki-era variation on the classic whiskey sour, created around 1960 at Steve Crane's Kon-Tiki chain of restaurants. Crane, a Beverly Hills restaurateur, had partnered with Sheraton Hotels to open Kon-Tiki outposts across North America as rivals to Trader Vic's and Don the Beachcomber, the two dominant tiki restaurant brands of the era. Rather than following the standard sour formula of spirit, citrus, and sweetener, the drink took the format in a tropical direction by splitting the citrus between grapefruit and lime juice and adding falernum, a spiced Caribbean syrup or liqueur, as part of the sweetening, on a base of rye whiskey.
A Western Sour is made with rye whiskey, fresh pink grapefruit and lime juice, falernum liqueur, and sugar syrup, shaken with ice and strained over crushed ice. It is garnished with a lime wheel and a maraschino cherry.
The most common mistake is over-pouring the sweet or liqueur component, which flattens the citrus balance; measure the falernum and sugar syrup precisely rather than free-pouring. A weak shake is the second issue, since a quick or gentle shake leaves the juice under-chilled and the texture thin once it meets the crushed ice.
