Ingredients
Method
Build the layers
- Fill a tall cocktail glass with ice cubes to the top for crisp layer separation.
- Pour grenadine syrup slowly over the ice so it settles at the bottom as the red layer.
- Hold a bar spoon just above the ice and slowly pour coconut rum or vanilla vodka over it to create the white middle layer without mixing.
- Pour blue raspberry vodka or blue curaçao over the spoon again to float as the top layer.
- Add a small splash of lemon-lime soda and garnish with a maraschino cherry and striped straw—do not stir before serving.
Notes
Pro tip: Pour slowly and keep the spoon hovering to protect each layer from sinking or bleeding. Serve immediately for the cleanest separation; store any leftovers covered in the fridge up to 1 day (layers will blend). Freezing is not recommended because carbonation from the lemon-lime soda will be lost; for a lower-sugar swap, use sugar-free lemon-lime soda.
