Notes
To Make the Ginger Honey Syrup
Peel four inches fresh ginger root and slice into small pieces no more than ¼ inch thick.
Add ginger to saucepan with water and honey over medium-high heat and stir until honey is dissolved.
Bring mixture to a boil then remove from heat. Steep honey ginger syrup for at least 30 minutes, to allow flavor to infuse. Makes about 16 ounces.
PreparationAlthough shrub concentrates are typically steeped for a while before serving, because of the sparkling water in this drink, I do not recommend preparing ahead of time.To large batch, muddle 24 mint leaves with 3 ounces honey syrup in a pitcher or carafe. Add in ice then 2 ounces apple cider vinegar with the mother, 2 cups grapefruit juice, and about 12 ounces of sparkling water. Stir to combine. Serves four.
