Fill a highball or balloon glass half full with ice cubes. Pour in the rhubarb syrup and the gin. Top with tonic water. Garnish with a slice of lemon and a rhubarb stalk.

The use of rhubarb-infused gin or rhubarb tonic water is nice but not mandatory. The rhubarb flavour is mostly supplied by the syrup so regular gin and tonic water will also deliver a great taste.The nutritional information provided is made by an online calculator and only meant as a guideline.
