Grapefruit Rosemary Simple Syrup
What really makes this grapefruit mocktail special is the syrup. This homemade grapefruit rosemary simple syrup is gently sweet, aromatic, and full of flavor, with hints of rosemary, ginger, and fresh grapefruit. It's incredibly versatile and just as delicious mixed with sparkling water or used in other mocktails.

Tips
- Use fresh grapefruit: Freshly squeezed juice tastes brighter and more balanced than store-bought versions.
- Let the syrup rest: The rosemary simple syrup becomes even more aromatic if you let it steep overnight in the fridge.
- Adjust sweetness to taste: Grapefruit can vary in bitterness, so feel free to add more or less syrup.
- Strain or don't strain: You can strain the syrup before using it, but leaving the rosemary and ginger in makes it more aromatic - and beautiful.
- Serve immediately: Add sparkling water just before serving to keep the drink nice and fizzy.
