Fresh rhubarb, sugar, and water are simmered into a sweet-tart rhubarb simple syrup. Keep a jar in the fridge for lemonade bars, cocktails, sparkling water, or anytime you need a little taste of spring.
In a large saucepan, combine the rhubarb, sugar, and water. Stir to combine.
Heat over medium heat. Once the mixture begins to boil, reduce the heat to medium-low and simmer for 10 minutes. Stir occasionally and watch carefully to prevent boiling over.
Remove the saucepan from the heat and let the mixture rest for 10 minutes.
Place a fine-mesh strainer over a large bowl. Pour the mixture through the strainer, then gently press the softened rhubarb with a wooden spoon to extract as much syrup as possible.
Allow the syrup to cool completely before transferring it to bottles or jars. This helps prevent excess condensation.
Storage: Store the rhubarb simple syrup in the refrigerator for up to 7 days. For longer storage, freeze in a freezer-safe container.
Notes
Note 1: Red or green rhubarb works. Fresh or frozen rhubarb works too. Defrost frozen rhubarb and drain off any excess liquid before simmering. How To Serve: Place syrup in a regular mouth mason jar and use a syrup dispenser for a mess-free serving option! Works great for lemonade bars, or to store in the refrigerator for quick and easy drinks!
