Fill a mixing glass with ice and chill for 30 seconds.
Add the vodka and ouzo to the mixing glass.
Stir continuously for 30 seconds until thoroughly chilled and diluted.
Strain into a chilled cocktail glass.
Garnish with a green olive.
Ouzo's anise intensity can vary significantly by brand - a drier, higher-proof ouzo like Ouzo 12 or Plomari will keep the cocktail crisp and spirit-forward, while sweeter expressions can tip the balance toward candy-like. Adjust the ouzo ratio to taste.
