The ginger is still the star of the show in this alcohol-free version of a classic Moscow mule. The lime adds acidity and combining the two in an easy to make syrup ensures balance.
For the ginger-lime syrup:
Combine ingredients in a saucepan and heat on medium until sugars dissolve. You can store it, covered, up to two weeks.
For the mocktail:
In a shaker, combine the ginger-lime syrup and soda water. Stir gently, then strain over ice in a Collins glass. Garnish with a lime wheel and a piece of candied ginger.
