If you can't find fresh lychees, use well-drained canned ones. For additional flavor, use orange vodka. Makes 1 serving.
In shaker, place 4 lychees and ginger. Muddle to break up ginger and mash lychees. Add vodka, simple syrup and a few ice cubes. Cover shaker and shake 4 to 5 times. Strain into martini glass. Garnish with 2 fresh lychees and mint sprig. Serve immediately.
