Booster – Blue Brandy Sour with Curaçao
A bold modern sour, the Booster fuses smooth brandy, citrus-bright blue curaçao, and just a whisper of lemon for a rich, electric-blue cocktail that’s silky, striking, and surprisingly easy to make.
A Blue-Hued Brandy Sour
The Booster reinvents the classic Brandy Sour in vivid color. Blue curaçao lends citrus sparkle and eye-catching hue, while brandy provides a warming, oak-tinged backbone. A touch of lemon balances the sweetness, and a shaken egg white delivers that smooth, creamy crown.
What You’ll Need
