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.
