Add vodka, raspberry liqueur, and fresh pineapple juice into a cocktail shaker.
Fill the shaker with ice and shake vigorously for 10–12 seconds until well chilled.
Double-strain into a chilled cocktail glass.
Express the oils from a lemon peel over the surface of the drink, then discard or rest on the rim as garnish.
Fresh pineapple juice is key here - it contains bromelain, a natural enzyme that creates a beautiful frothy head when shaken vigorously, giving the drink its signature silky texture. Avoid carton juice if you want that foam.
