To make the ginger simple syrup, combine sugar and water in a medium saucepan over medium-high heat, stirring to dissolve the sugar. Add ginger and bring the liquid to a simmer. Remove from heat and let steep for 30 minutes. Strain into an airtight container and refrigerate up to one month.

Combine vodka, Pama, and 3 ounces of the ginger syrup in tall glass fill with ice and stir to combine. Strain into two martini glasses to serve.
