Blue Lagoon Mocktail Recipe: The Classic Way and the 10-Second Way
The electric-blue drink everyone photographs before they sip. Here is how to make it from scratch, how to batch it for a crowd, and how to skip the prep entirely.
What is a Blue Lagoon mocktail?
The original Blue Lagoon is a cocktail of vodka, blue curaçao and lemonade, usually credited to Harry's New York Bar in Paris. Its colour made it a bar-menu favourite, and in India it has become one of the most-ordered mocktails at cafés, weddings and house parties.
The mocktail version drops the vodka and keeps everything people actually love about it: the bright blue colour, a sweet-and-sour citrus flavour and plenty of fizz. The blue comes from blue curaçao syrup, an orange-flavoured syrup coloured blue. Make sure you buy the syrup and not the liqueur, which contains alcohol.
Classic Blue Lagoon mocktail recipe
Blue Lagoon Mocktail
Ingredients
- 30 ml blue curaçao syrup (non-alcoholic)
- 15 ml fresh lemon juice (about half a lemon)
- 150 ml chilled lemon-lime soda, or soda water plus 1 tsp sugar syrup
- A handful of ice cubes
- 1 lemon wheel and a mint sprig, to garnish
Method
- Fill a tall glass to the top with ice.
- Pour in the blue curaçao syrup and the lemon juice.
- Top up slowly with the chilled soda.
- Stir gently once or twice so the colour evens out without losing the fizz.
- Garnish with a lemon wheel and a mint sprig and serve straight away.
That's it. The balance to aim for is roughly 2 parts syrup to 1 part lemon, then soda to taste. If your soda is already sweet (like Sprite or 7UP), you can cut the syrup down a little.
Tips for a better Blue Lagoon
- Chill everything. Cold soda keeps its fizz longer and the ice melts slower, so the drink doesn't get watery.
- Use fresh lemon. Bottled lemon juice tastes flat. Half a fresh lemon makes a noticeable difference.
- Pour soda last and slowly. Tilting the glass while pouring keeps more of the bubbles.
- Try a sugar rim. Run a lemon wedge around the rim and dip it in sugar for that café look.
- Go for a clear, tall glass. Half the appeal of a Blue Lagoon is seeing that colour.
Blue Lagoon variations to try
Blue Lagoon lemonade
Swap the soda for still, chilled nimbu pani for a softer, less fizzy drink that works well at lunch.
Masala Blue Lagoon
Add a pinch of chaat masala and a pinch of kala namak before topping up. It sounds odd, but the salty-tangy kick works brilliantly with the sweet citrus.
Blue Lagoon with mint and cucumber
Drop in a few thin cucumber slices and torn mint leaves for something more refreshing on a hot afternoon.
Making Blue Lagoon for a party
For a 1.5-litre jug (about six glasses), mix 180 ml blue curaçao syrup with 90 ml lemon juice in the jug and keep it in the fridge. Add 1 litre of chilled soda only when guests arrive, so it doesn't go flat. Serve over ice in each glass rather than in the jug, which waters the whole batch down.
Host hack: set out glasses, ice and a bowl of lemon wheels and let guests top up their own. It frees you up and the drink is always fizzy.
The 10-second way: Partay Blue Lagoon
If you don't want to buy a whole bottle of syrup for one evening, Partay Blue Lagoon is an instant mocktail mix in a 3 g sachet. Tear it open, pour it into a glass, add about 200 ml of chilled water or soda, stir and add ice. You get the same bright blue drink with 7 calories per serving, for ₹20 a sachet.
For a party, one sachet makes one glass, so 20 guests having three drinks each is 60 sachets. A sachet fits in a pocket, so you can carry the party to a picnic, a hostel room or a road trip too.
One ₹20 sachet + 200 ml water or soda = a 7-calorie, alcohol-free mocktail in 10 seconds. In select stores in Gurugram & Alwar, with bulk orders shipped Pan India.
Blue Lagoon mocktail FAQs
Does a Blue Lagoon mocktail contain alcohol?
No. The mocktail uses blue curaçao syrup, which is non-alcoholic. Only the cocktail version uses vodka and curaçao liqueur. Partay Blue Lagoon is also completely alcohol-free.
What does a Blue Lagoon taste like?
Sweet and citrusy, with a light orange note from the curaçao and a sharp lemon finish. The soda keeps it light and fizzy.
What can I use instead of blue curaçao syrup?
For the flavour, a little orange squash with lemon works, though you lose the colour. A Blue Lagoon instant mix like Partay gives you both without needing the syrup.
Where can I buy blue curaçao syrup in India?
Many supermarkets and online grocery apps stock it in the syrups and mixers section. Check the label says syrup, not liqueur.
