- 1 cup water
- 1 cup sugar
- 3-4 sprigs rosemary (roughly torn)
- Pink grapefruit juice (100% juice, not from concentrate)
- Club soda
For the rosemary-infused simple syrup, bring the water and sugar to a boil in a small saucepan. Stir on medium to high heat until the sugar is completely dissolved. Throw in the torn sprigs of rosemary and place lid on pan. Allow to steep for about an hour or until cool. Using a sieve, strain the syrup in an airtight storage container. Store in fridge until chilled.
Fill each glass one third full of grapefruit juice. Add ice and 2-3 tablespoons of the simple syrup and give it a stir. Top off with club soda and garnish with a grapefruit wedge and sprig of rosemary.
Leftover simple syrup can be stored in the fridge for 2-3 weeks.
