Step-by-Step Instructions
- Fill the Glass:
- Fill a 15-ounce daiquiri or hurricane glass about three-quarters full with crushed ice. This keeps the drink cold and sets a nice base.
- Shake the Ingredients:
- In a cocktail shaker filled with ice, combine one and a half ounces of Malibu coconut rum, one ounce of 100 percent pineapple juice, and half an ounce of blue curacao. Secure the lid and shake vigorously for 15 to 20 seconds until the mixture is well blended and chilled.
- Strain the Mixture:
- Strain the shaken cocktail carefully into the ice-filled glass. This filters out any small ice shards and keeps the drink smooth and enjoyable.
- Add the Lemon-Lime Soda:
- Slowly pour half a cup of lemon-lime soda over the cocktail. Watch as it creates a light foamy layer on top, resembling white caps on ocean waves due to the carbonation.
- Garnish and Serve:
- Place a straw and if you like, a colorful cocktail umbrella for decoration. Serve immediately to enjoy the fresh fizzy texture and tropical flavors.

My favorite part is how the blue curacao creates that stunning ocean blue color that immediately transports me to a beachside retreat. Making this drink reminds me of a fun summer trip when I first discovered how simple it is to impress guests with bright flavors and colors.
Storage Tips
This cocktail is best served fresh so the carbonation stays vibrant. If you want to prepare elements ahead, keep the rum and juice mixture chilled in the refrigerator but add soda just before serving. Avoid pre-mixing with soda to maintain fizz and flavor integrity.
Ingredient Substitutions
If you do not have blue curacao, you can try orange curaçao with a few drops of blue food coloring to mimic the look, though the flavor may differ slightly. For a non-alcoholic version, replace the coconut rum with coconut water or coconut-flavored syrup and omit the blue curacao or use a blue-colored non-alcoholic syrup.
Serving Suggestions
Pair this cocktail with light tropical appetizers like grilled shrimp skewers or fresh fruit platters to keep the mood vibrant and refreshing. It also complements spicy or savory dishes by balancing heat with sweetness and bubbles.
Cultural and Historical Context
