Method

• 

  Step 1

  Freeze a coupe or martini cocktail glass while you scoop the flesh from one half of the passion fruit into a cocktail shaker; set the remaining half aside for garnish.

• 

  Step 2

  Combine the vodka, bianco vermouth, passion fruit syrup, sugar syrup and vanilla bitters along with the pulp in the shaker.

• 

  Step 3

  Fill with ice cubes and secure the cover tightly; shake vigorously for 15-20 seconds or until the mixture is completely chilled and foamy.

• 

  Step 4

  Double-strain the bright drink into a chilled glass, add the saline solution to the drink and garnish with the remaining passion fruit half, either on the rim or floating in the glass. Serve right away.
