Blue Lagoon drink backstory

I have been blessed to have taken several Caribbean cruises over the last few years. One of my very favorite things about those vacations is sitting on the balcony, sipping a fruity tiki drink, and just watching the color of the ocean turn to a gorgeously indescribable blue color as we get closer to our destinations.

It’s Heaven.

Since I have a workload that would overwhelm the biggest workaholic AND I gave the family a Caribbean cruise for Christmas, there will be no cruising for me this summer.  Thankfully it doesn’t mean there won’t be some fabulously cruise-worthy drinks like this Blue Lagoon in my future.

Best of all, I can keep it all low carb. Yay!

So y’all know that I use Torani Sugar Free Syrups a lot. I use them in ice cream, I use them in all kinds of desserts, I add the pineapple sugar free syrup to cottage cheese, and I create amazing 0 carb cocktails every single weekend. There are so many. syrups! They have over 100 flavors and many of them also come in sugar free versions.

Tiki Cocktail FAQs

This Blue Lagoon drink can definitely be classified at a tiki drink because of the addition of rum as well as the tropical vibe.

What’s in Blue Lagoon, the Cocktail?

The traditional version is basically vodka Blue Curacao, and lemonade – I posted an Spiked Lemonade that’s very similar. This is not the traditional version but I think it retains the spirit (get it? Spirit?) of the original. The original Blue Lagoon drink is believed to have been created in Harry’s New York Bar in Paris.  

What is Tiki style?

Tiki drinks because popular in the middle of the 20th century – the 1950s and 60s. It is used in Polynesian style restaurants and clubs that were especially popular during that time. Between Hawaii becoming a state in 1959 and Elvis’s movie, Blue Hawaii, we developed an obsession with all things tropical from pink flamingos to tiki drinks!  You can use a highball glass, a hurricane glass, any tall glass, or a stemless wine glass like I did. A cocktail shaker isn’t required, but it helps mix things.

What Makes a Drink Tiki?

  • Rum. Although there are lots of drinks called tiki drinks that don’t have rum it is considered one of the signatures of a good tiki cocktail.
  • Fruit Juice. Ok, this one is kind of out when you are doing low carb but with all of the Torani flavor possibilities you can come up with a pretty good adaption like I did in this Blue Lagoon cocktail.
  • Layers of Flavor. There should be sweet, tangy, spicy… whatever you like but more than one flavor so it’s like a parade of tastes.

Blue Lagoon Drink

Are you ready for this low carb blue cocktail? It’s a sweet combination of tropical and tangy flavors mellowed with a touch of almond. This blue cocktail recipe is so refreshing when it’s hot, it’s the perfect drink for summer. If you like a less sweet cocktail use club soda and sugar free tonic. For a sweeter cocktail use sugar free ginger ale or lemon-lime soda and leave out the tonic. Of course, you can have a Maraschino cherry on top, just don’t eat it.  A Maraschino cherry has almost 2 grams of sugar.  The traditional Blue Lagoon drink uses Blue Curacao.  It’s tasty, but one ounce of Blue Curacao has 5 grams of sugar.  Using flavored vodkas and sugar free syrups gives you all the flavor of Blue Curacao without the sugar. There’s no need for blue food coloring as the sugar free raspberry turns it blue (I was surprised too !). 

The regular blue drink recipe calls for lemonade which is usually full of sugar, that’s where the pineapple sugar free syrup comes in.  It also uses a lemon wheel for garnish which I like.  A lime slice or lemon slice adds that citrus flavor that really makes you feel like you are in the tropics.
