Exploring the Whiskey Sour
The Whiskey Sour is a classic cocktail that has stood the test of time, with its origins tracing back to the 19th century. The combination of bourbon, lemon juice, and simple syrup creates a delightful balance of flavours, with the bourbon’s robust character complemented by the tart citrus and the sweetness of the syrup.
Essential Ingredients
At the heart of the Whiskey Sour are the core ingredients: 2 oz (60ml) of bourbon or whiskey, ¾ oz (22.5ml) of fresh lemon juice, and ½-¾ oz (15-22.5ml) of simple syrup or ⅔ oz (20ml) of a rich 2:1 sugar syrup. The choice of bourbon or whiskey can make a significant difference, with recommendations including Elijah Craig Small Batch (94 proof), Woodford Reserve, Bulleit, Buffalo Trace, and Cody Road. Fresh lemon juice is essential, as it provides a brighter, more vibrant flavour profile compared to bottled lemon juice.
Mastering the Ratios
When it comes to the classic Whiskey Sour, there are several preferred ratios to consider. Difford’s Guide suggests a 6:3:2 ratio (6 parts/60ml/2oz whiskey, 3 parts/30ml/1oz lemon, 2 parts/20ml/â…”oz rich syrup), which produces a well-balanced drink. For a sourer version, a 4:2:1 ratio (60ml whiskey, 30ml lemon, 15ml rich syrup) works well, while a whiskey-forward version can be achieved with an 8:3:2 ratio (60ml whiskey, 22.5ml lemon, 15ml rich syrup).
Garnishes and Serving
The Whiskey Sour is traditionally garnished with a few dashes of Angostura bitters, which add a subtle complexity to the drink. An orange slice and a maraschino cherry (the “cherry flag”) also make a classic garnish. For a New York Sour variation, a red wine float can be added, which creates a visually striking and flavourful twist. The Whiskey Sour is typically served in a rocks glass over ice or in a chilled coupe glass.
Dietary Considerations
The Whiskey Sour is a relatively high-calorie cocktail, with Difford’s recipe coming in at approximately 227 calories per serving. However, there are lower-calorie variations available, such as a Splenda-sweetened version that clocks in at 140 calories. For those with dietary restrictions, the egg white can be omitted, and a vegan option using Fee Foam cocktail foamer can be used instead.
Step-by-Step Instructions
Creating the perfect Whiskey Sour is a straightforward process:
1. Add the whiskey, lemon juice, and syrup (along with the egg white, if using) to a shaker and dry shake for 15-30 seconds to emulsify the egg white.
2. Add ice to the shaker and shake for 6-20 seconds until chilled.
3. Double strain the cocktail into a rocks glass over ice or a chilled coupe glass.
4. Garnish with 3-4 drops of Angostura bitters, an orange slice, a maraschino cherry, and/or a lemon peel twist. For a New York Sour, carefully float a red wine over the back of a spoon.
By following these simple steps, you can craft the perfect Whiskey Sour that captures the essence of this beloved classic cocktail.
Conclusion
The Whiskey Sour is a timeless and versatile cocktail that has stood the test of time. By mastering the essential ingredients, understanding the preferred ratios, and following the step-by-step instructions, you can create a balanced and delicious Whiskey Sour that will impress your guests and satisfy your taste buds.
