Chill your martini glass by placing it in the freezer for 10–15 minutes or filling it with ice water while you prepare the drink.
Add 2 ounces good quality vodka, 1 ounce lychee liqueur, and 1 ounce lychee syrup (from canned lychees) into a cocktail shaker.
Fill the shaker two-thirds full with ice, secure the lid, and shake vigorously for 15–20 seconds until the shaker feels frosty.
Discard the ice or water from the chilled martini glass, strain the cocktail into the glass, and drop 1–2 canned lychees into the drink for garnish.
