Tropical Blue Cocktail – Blue Rumba

Home » COOK » Recipes » Beverages » Cocktails » Tropical Blue Cocktail – Blue Rumba

This Tropical Blue Cocktail (that I’ve named Blue Rumba!) is like a tropical island in a glass! So many tropical drinks start with rum, and this one is no different!

The addition of fruity liqueurs and a citrus garnish makes it a delicious cocktail for hot summer days by the pool or as a signature beverage for your tropical and Hawaiian parties!

Tropical Blue Cocktail

The full ingredients list and instructions are found in the printable recipe card at the end of this post. I highly recommend reading the blog post all the way through so that you don’t miss any tips or substitution suggestions and to ensure that you have all the ingredients and equipment required as well as understand the steps and timings involved.

I think by now we all know my obsession with tropical flavors, considering the amount of tropical food and drink recipes I have on The Purple Pumpkin Blog!

I decided to call this Summer Rum Cocktail a Blue Rumba because its main liquor is rum, and it also contains banana liqueur – and of course, it’s a blue cocktail!

The Blue Rumba gets its color from Blue Curaçao, a liqueur made with the dried peels of the Laraha citrus fruit, grown only on the island of Curaçao.

It is naturally colorless but is often given artificial coloring, most commonly blue, making it really handy to use in this drink!

You can use this recipe to make a single drink, or to scale up to make a big batch of tropical blue cocktails – perfect for parties and luaus!

Ingredients Used In This Cocktail

For your convenience, I’ve linked any specialized ingredients needed for this recipe to Amazon below.

You can use any rum that you like in this cocktail – you could use a regular white rum, or try a coconut or pineapple rum, or even a mixture of rums – your choice and depending on what you have in your liquor cabinet!

Don’t worry if you don’t have a cocktail shaker, you could just use a container with a tight-fitting lid – like a mason jar, water bottle, or even the cup on a blender or smoothie maker.

Blue Rumba Variations

I like to try and give variations on the cocktails shared on The Purple Pumpkin Blog, and especially turn the cocktail into a mocktail so that non-drinkers (and kids if suitable) can enjoy the drink too!

Virgin Blue Rumba Mocktail (non-alcoholic)

So that non-drinkers and kids can enjoy a glass of this blue cocktail, we can turn it into a mocktail by making a few switches.

I love the Monin brand of syrups as there are lots of flavors and they are a very versatile ingredient that can be used in cocktails, mocktails, coffee, cocoa, shakes, smoothies, and more.

Of course, syrups add a sweetness that you may not necessarily get from alcoholic spirits, so use the syrups to your personal taste preference.

To make a virgin cocktail follow the recipe in the card at the end of this post and replace the rums with Pineapple Juice, and use blue curaçao syrup and banana syrup in place of the two fruit liqueurs. The coconut water and lemon-lime soda remain the same.

Frozen Blue Rumba

Want to turn this blue cocktail into a frozen blue slushie? Easy!

Put all the ingredients in a blender with a generous amount of crushed ice – then blend till smooth.

Serve with a straw, and watch out for brain freeze!

You can turn the mocktail into a slushie too in the same way.

Blue Rumba Party Punch

If you want to make Blue Rumba for a crowd, you can make a large batch of the cocktail no problem!

As long as you use the same measuring container (glass, cup, jug, etc) for the “1 part”, the ratios will be correct and you can make as much as you need to.

Serve in drinks dispensers, or pitchers, or go really retro and serve it from a punch bowl!

Make sure you add plenty of ice to your serving container of choice and add maraschino cherries and slices of orange, lemon, and limes as garnish. Or leave a bowl of them on the side for guests to garnish their drinks

To make a batch of this tropical blue cocktail party punch, mix together:

  • 2 parts White Rum, Coconut Rum or Pineapple Rum (or a mixture of them)
  • 1 part Creme de Banane
  • 1 part Blue Curaçao
  • 1 part Coconut Water
  • 2 parts Lemon-Lime Soda

This cocktail recipe is intended for adults of the legal drinking age in your country of residence.
Please drink responsibly. Do not drink and drive.
