The Charred-Lemon Gin Sparkler is a refreshing and citrusy cocktail that is perfect for summer gatherings. The charred lemon adds a smoky and caramelized flavor to the drink, while the gin provides a botanical and juniper note. The sparkling water adds a fizzy and bubbly texture, making it a delightful and thirst-quenching beverage. Serve it over ice and garnish with a lemon slice for a visually appealing presentation.
