This rhubarb simple syrup with ginger is a vibrant, tart-sweet syrup that captures the bold flavor of fresh rhubarb at its peak. Bright pink rhubarb and warm fresh ginger are simmered low and slow with sugar and water until the flavors deepen and meld into something truly special. Stir it into sparkling water, lemonade, cocktails, or mocktails for an instant seasonal upgrade. Make a batch at the start of the week and keep it in the fridge all spring long.
