Tropicana Cocktail

Fill a cocktail shaker halfway with ice cubes.

Pour the light rum, pineapple juice, and grapefruit juice into the shaker.

Secure the shaker lid and shake vigorously for 10-15 seconds until well chilled.

Strain the mixture into four rocks glasses filled with fresh ice.

Add a dash of grenadine to each glass, allowing it to settle for a subtle layered effect.

Serve immediately and stir gently before drinking.
