Method
Build the tri-color layers
- Fill a tall cocktail glass with ice to the top so there’s room for three layers without overflow.
- Pour grenadine syrup slowly over the ice; let it settle 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.
- 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, then serve immediately without stirring.
Notes
For the cleanest separation, pour each liquid slowly and over the spoon edge so the next layer floats rather than mixes. Refrigerate any leftover components (grenadine and soda) but the assembled cocktail should be served right away—ice-and-layer separation won’t hold. Freezing isn’t recommended for the finished drink. For a lighter option, use vanilla vodka instead of coconut rum and choose diet lemon-lime soda.
