Why This Recipe Works (Quick Science)
The rosemary simple syrup pulls flavor from the rosemary leaves using heat. The sugar balances the tart lemon juice, while the gin carries the herbal aromas. Sparkling water adds carbon dioxide bubbles that lift flavors toward your nose, making the drink taste brighter and more refreshing.
Recipe Instructions
Step 1: Make the Rosemary Syrup
Add 2 fresh rosemary sprigs, 2 tablespoons granulated sugar, and 2 tablespoons water to a small saucepan. Heat over medium-low heat for about 5 minutes, stirring until the sugar dissolves completely. Remove from heat and let the rosemary steep for another 5 minutes.
Step 2: Strain and Cool the Syrup
Pour the warm rosemary syrup through a fine mesh strainer into a small bowl. Discard the rosemary sprigs and allow the clear rosemary syrup to cool for a few minutes.
Step 3: Mix the Cocktail
Fill a cocktail shaker with 2 cups ice cubes. Add 4 ounces gin, 2 ounces freshly squeezed lemon juice, and the cooled rosemary syrup. Shake for 15 seconds until chilled.
Step 4: Pour and Add Bubbles
Divide the shaken mixture evenly between 2 highball glasses filled with fresh ice cubes. Top each glass with 4 ounces sparkling water.
Step 5: Garnish and Serve
Garnish each drink with 1 lemon wheel and 1 fresh rosemary sprig. Serve immediately.
