Rosemary Grapefruit Spritzer: Crisp

Instructions:

1. Combine the sugar and water in a small saucepan over medium heat. Stir until the sugar crystals completely dissolve.
2. Add the rosemary sprigs and bring to a gentle simmer. Let it bubble softly for 5 minutes until the liquid smells fragrant and woodsy.
3. Remove from heat and let the rosemary steep for another 10 minutes.
4. Strain through a fine-mesh sieve into a jar and cool for 1 hour.
5. Squeeze fresh grapefruit and lime juice, avoiding pressing too hard on the white pith.
6. In a highball glass or champagne flute, pour in 4 oz fresh grapefruit juice, 1 oz chilled rosemary syrup, and 1/2 oz lime juice.
7. Top with 4 oz chilled club soda.
8. Garnish with a 2-inch rosemary sprig and a thin slice of grapefruit.
