Ingredients Equipment Method Notes

Ingredients
  

  • 1.5 cups pineapple soda or pineapple sparkling water Must be carbonated for the foam and swirl effect
  • 2 tablespoon mango syrup or passion fruit syrup Stirred into the soda before pouring over ice
  • 0.5 cup coconut cream or coconut-flavored coffee creamer Slightly thicker than milk for a slower, more vivid swirl
  • 1 teaspoon vanilla extract Stirred into the coconut cream before pouring
  • ice cubes Added to the glass before the soda
  • 1 clear glass straw Inserted at an angle as shown in the image

Equipment

  • 1 tall clear pint glass or Collins glass Clear glass shows the swirl pattern through the sides
  • 1 small pitcher or measuring cup For mixing the soda and syrup base
  • 1 Small bowl For mixing the vanilla into the coconut cream
  • 1 Spoon For the over-the-back pour technique
  • 1 clear glass straw Shows the drink color through the straw
  • 1 Measuring spoons

Method
 

  1. Stir the mango or passion fruit syrup into the pineapple soda in a small pitcher until evenly combined, then fill a tall clear pint glass with ice cubes.
  2. Pour the pineapple soda and syrup mixture slowly over the ice so the carbonation is preserved and the glass fills to about three quarters full with room for the cream above.
  3. Stir the vanilla extract into the coconut cream in a small bowl until fully combined and check that the cream flows in a thin slow ribbon rather than in clumps before using.
  4. Hold a spoon face down just above the surface of the soda with the tip resting lightly on the top ice cube, then pour the vanilla coconut cream slowly over the back of the spoon in a thin steady stream.
  5. Watch the white cream sink slowly through the yellow soda in flowing ribbons that create the marble swirl pattern visible in the image, then do not stir so the pattern continues to evolve naturally.
  6. Let the drink sit for 30 seconds so the foam at the top settles, then insert the clear glass straw at an angle against the side of the glass as shown in the image and serve immediately.

Notes

Pour the coconut cream over the back of a spoon held just above the surface of the soda for the swirl effect. Do not stir after adding the cream. Let the drink sit for 30 seconds before inserting the straw so the foam settles. Serve immediately for the most vivid swirl.
