The Shamrock Sour is a vibrant green twist on the classic whiskey sour, blending smooth Irish whiskey, zesty citrus, and a hint of sweetness for a perfectly balanced cocktail. This festive drink is a must-have for St. Patrick’s Day celebrations, offering a bright and tangy flavor with a soft, velvety texture.
Unlike a traditional whiskey sour, the Shamrock Sour gets its signature green hue from Midori melon liqueur, green chartreuse, or natural ingredients like spinach juice. The result is a smooth, sweet-tart drink with an eye-catching appearance—ideal for festive gatherings, cocktail parties, or anytime you want a delicious whiskey-based drink with a fun, modern twist.
Ingredients
For the Shamrock Sour:
- 2 oz Irish whiskey – A smooth, slightly sweet whiskey pairs best.
- ¾ oz fresh lemon juice – Adds a bright, tangy contrast.
- ½ oz Midori (or green chartreuse) – For a subtle melon flavor and a vibrant green hue.
- ½ oz simple syrup (or honey syrup) – Balances the acidity with a touch of sweetness.
- 1 egg white (optional, for frothiness) – Creates a silky, foamy top layer.
- 1-2 dashes orange bitters – Enhances the citrus and whiskey notes.
- Ice cubes – For shaking and chilling.
For Garnish:
