Instructions
Add all ingredients to a heavy saucepan and bring to a boil. Lower heat and simmer gently, stirring occasionally for about 20 minutes, or until rhubarb breaks down.
Remove from the heat and strain into a bowl through a strainer.
Cool syrup completely, then transfer to a sealable container, and store in refrigerator for up to 2 months.
Notes
Use syrup, to taste, to make mocktails with sparkling mineral water and quarter of lime. Add mint for a change of flavors.
