Bring water to a boil. Add sugar and stir until sugar has dissolved.
Add fresh rosemary to the syrup. Remove from heat, set aside and allow the mixture to cool to room temperature.
Once it’s cooled, remove the rosemary from the syrup with a fork.
Discard the rosemary. Pour the syrup into an airtight container and refrigerate.
When kept in the refrigerator, the syrup will keep for 2 weeks.
Enjoy!
Notes
Note: For stronger rosemary flavor, you can leave the sprig of rosemary in the syrup. This will cause the syrup to spoil faster, so I do recommend removing the rosemary after 24 hours.
