Cocktail
Rosemary Simple Syrup (makes ~1 cup)
Method
Rosemary Simple Syrup (prepare ahead)
Combine
In a small saucepan, combine 1 cup water and 1 cup granulated sugar.
Heat
Place over medium heat and stir until the sugar fully dissolves and the mixture comes just to a simmer (do not boil vigorously), about 3–5 minutes.
Infuse
Remove from heat, add 3 fresh rosemary sprigs to the hot syrup, and let steep for 20–30 minutes depending on how assertive you want the rosemary flavor (longer = stronger).
Strain & Cool
Strain out the rosemary, transfer the syrup to a clean jar, cool to room temperature, then refrigerate. Syrup will keep in the refrigerator for up to 2 weeks.
Cocktail Assembly
Chill Glass
If desired, chill a highball or Collins glass by filling it with ice water while you prepare the drink, then discard the water before assembling.
Measure & Build
Fill the glass with fresh ice (about 1 cup). Pour in 3 oz fresh grapefruit juice and 0.75 oz rosemary simple syrup.
Top with Soda
Gently top the mixture with 2 oz soda water. Stir once briefly (1–2 gentle stirs) to combine without flattening the carbonation.
Garnish
Garnish with a fresh grapefruit wedge on the rim and a sprig of rosemary. For extra aroma, slap the rosemary sprig between your palms to release oils before placing it in the glass.
Serve
Serve immediately while cold and effervescent. Adjust sweetness by adding more or less syrup to taste (±0.25 oz).
