Notes
Store leftover rosemary simple syrup in an airtight container in the refrigerator for up to 2 weeks.The cocktail can be made non-alcoholic by replacing prosecco with sparkling water or ginger ale.Fresh grapefruit juice makes a big difference in taste compared to store-bought juice.For a stronger rosemary flavor, let the simple syrup steep longer before straining.
