Add the vodka, lime juice and ginger syrup to a shaker and fill with ice. Shake, and strain into a mule mug or Collins glass filled with fresh ice. Top with club soda and mound crushed ice over the top of the drink.
*Ginger syrup INGREDIENTS:
.5 cups Fresh ginger juice (squeezed from freshly grated ginger root)
1 cup Superfine sugar
In a small saucepan, heat the ginger juice until warm (but do not let boil) over low heat. Add the sugar and whisk until the sugar is dissolved. Store the syrup in a lidded container in the refrigerator until ready to use.
