Whether you’re hosting a party or want something special on a Tuesday night, this mocktail delivers. It’s easy to make, light on the palate, and guaranteed to get compliments.

Why This Recipe Works

This drink balances sweet pineapple and creamy coconut with a strong, citrusy sour note. That balance keeps it from tasting syrupy or heavy.

Blue curaçao syrup adds the signature color and a bright orange flavor, while fresh lime juice delivers the tart edge that makes each sip lively. Using coconut water instead of heavy coconut milk keeps the texture crisp and hydrating. A touch of simple syrup helps you control sweetness based on the ripeness of your pineapple juice.

Finished with crushed ice and a zesty garnish, it’s refreshing, eye-catching, and easy to batch for a crowd.

Shopping List

• Pineapple juice (100% juice, not from concentrate if possible)
• Coconut water (chilled)
• Blue curaçao syrup (non-alcoholic)
• Fresh lime juice (about 2–3 limes)
• Simple syrup (optional, to taste)
• Club soda or sparkling water (for topping)
• Ice (crushed or pebble ice works best)
• Garnishes: pineapple wedge, lime wheel, maraschino cherry, fresh mint
• Salt or coconut sugar (optional, for rimming)

Step-by-Step Instructions

1. Chill everything first. Pop your juices, coconut water, and club soda in the fridge. Cold ingredients make a better mocktail and help preserve fizz.
2. Prep your garnish. Slice lime wheels, cut pineapple wedges, and pick a few mint sprigs. Set aside on a small plate so you’re ready to assemble.
3. Optional: Rim the glass. Run a lime wedge around the rim of a tall glass.Dip into coarse salt or coconut sugar for a fun finish and subtle flavor contrast.
4. Fill with crushed ice. Add ice to the top. Crushed or pebble ice chills the drink quickly and creates a frosty texture.
5. Mix the base. In a shaker (or mixing glass), combine 4 ounces of pineapple juice, 2 ounces of coconut water, 1 ounce fresh lime juice, and 0.75 ounce blue curaçao syrup. Add ice and shake briefly until cold.
6. Taste and adjust the sweetness. If you prefer a sweeter drink, add 0.25–0.5 ounce simple syrup.If it’s too sweet, add a splash more lime juice.
7. Strain into the glass. Pour the blue mixture over the crushed ice.
8. Top with bubbles. Add 1–2 ounces of club soda to lift the flavors and add a light fizz. Stir gently to combine.
9. Garnish and serve. Add a lime wheel, pineapple wedge, cherry, and a sprig of mint. Serve immediately with a straw or swizzle stick.

Storage Instructions

For the best flavor, mix this mocktail fresh.

If you need to prep ahead, combine the still ingredients (pineapple juice, coconut water, lime juice, blue curaçao syrup) up to 24 hours in advance and keep refrigerated in a sealed container. Do not add club soda or ice until serving to preserve carbonation and avoid dilution. If you have leftovers, store the base (without soda) in the fridge for up to 48 hours.

Shake before using, as natural separation may occur. Fresh lime juice loses zest over time, so you may want to add a small splash of new lime juice before serving.

Health Benefits

This mocktail is alcohol-free, which helps you stay hydrated and clear-headed. Coconut water provides electrolytes like potassium, making it a refreshing option for warm days. Pineapple juice contains vitamin C and bromelain, an enzyme linked to digestive support. Using fresh lime juice adds antioxidants and brightness without heavy calories.

If you monitor sugar intake, you can control sweetness by adjusting the simple syrup and choosing unsweetened coconut water. Served over lots of ice and topped with club soda, it’s a lighter alternative to heavy, creamy drinks.

Common Mistakes to Avoid

• Over-sweetening. Pineapple juice and blue curaçao syrup are already sweet. Taste before adding simple syrup.
• Skipping fresh lime. Bottled lime lacks brightness.Fresh juice gives that crisp, sour pop that defines this drink.
• Using warm ingredients. Warm liquids melt ice fast and dull flavor. Keep everything cold for a sharper taste.
• Adding soda too early. Stir in club soda at the end to keep the fizz lively.
• Heavy coconut milk substitution. It can overpower the sour profile and make the drink feel heavy. Use coconut water for a cleaner finish.

Alternatives

• No blue curaçao syrup? Use a mix of orange syrup and a drop or two of natural blue food coloring or butterfly pea flower extract (add acidity to turn it bright).The flavor should lean orange-citrus.
• Less sugar. Choose unsweetened pineapple juice and skip the simple syrup. Add more lime for a drier, zestier sip.
• Herbal twist. Muddle a few mint leaves or basil in the shaker for a fresh, garden note.
• Spicy kick. Add a thin slice of jalapeño to the shaker, or rim the glass with Tajín for heat and tang.
• Creamier variation. Swap 1 ounce of coconut water for 1 ounce of light coconut milk. Keep the rest the same to avoid heaviness.
• Frozen version. Blend all base ingredients with a cup of ice until slushy.Top with a splash of soda in the glass.
• Batch for a crowd. For 8 servings, mix 4 cups pineapple juice, 2 cups coconut water, 1 cup fresh lime juice, and 6 ounces blue curaçao syrup. Chill, then pour over ice and top each glass with soda.

FAQ

Can I make this without blue curaçao syrup?

Yes. Use orange syrup or triple sec–flavored syrup (alcohol-free) for the citrus note, and add a drop of blue coloring if you want the signature look.

The taste will still be bright and tropical.

What type of pineapple juice works best?

Go for 100% pineapple juice, ideally not from concentrate. If using fresh-pressed juice, strain out pulp for a smoother sip.

How can I make it more sour?

Increase the fresh lime juice by 0.25–0.5 ounce and reduce or skip the simple syrup. You can also add a small pinch of citric acid for a clean, tart punch.

Is there a good substitute for coconut water?

Use filtered water plus a tiny splash of coconut extract, or swap in aloe vera juice for a gentle, clean profile.

Keep the extract light to avoid artificial flavors.

Can I use lemon instead of lime?

You can, but the flavor shifts. Lemon is softer and less tropical. If using lemon, add a little extra blue curaçao syrup to keep the citrus note pronounced.

How do I keep the color vibrant?

Build in a clear glass over white or light surfaces, use crushed ice, and stir gently after adding soda.

Avoid dark mixers that muddy the blue hue.

What glass should I use?

A highball or hurricane glass works well. The tall shape shows off the color and holds plenty of ice for a long, refreshing sip.

Is this kid-friendly?

Absolutely. It’s alcohol-free and fun to look at.

Just watch the sugar content and consider reducing syrup for younger palates.

Can I prep the garnishes ahead?

Yes. Slice lime wheels and pineapple wedges a few hours ahead and keep them in an airtight container in the fridge. Add mint at the last minute to keep it perky.

What if I don’t have a cocktail shaker?

Use a mason jar with a tight lid or stir the ingredients briskly in a measuring cup with ice.

Strain or pour over fresh crushed ice to avoid excess dilution.

The Sour Blue Hawaiian Mocktail is a bright, tart, and tropical drink that feels special without being fussy. It’s easy to customize, simple to batch, and gorgeous in the glass.
