Blue Curaçao Syrup (Non-Alcoholic)

One thing before anything else: this is not the alcoholic blue curaçao liqueur. It has no alcohol in it at all. What it is — a bright blue, orange-flavored sugar syrup — is a real, purchasable, non-alcoholic product: Torani and Monin both sell a bottled “Blue Curaçao” flavoring syrup in the same coffee-syrup aisle as their vanilla and caramel, built for exactly this use case (coffee drinks, sodas, and mocktails). This is our homemade version of that syrup, not of the liqueur it’s named after.

The Syrup

Combine 1 cup water and 1 cup granulated sugar in a small saucepan over medium heat, stirring until the sugar dissolves. Simmer for 2-3 minutes to make sure everything’s fully dissolved. Off the heat, stir in 1 tsp orange extract and 1/4 tsp citric acid if using — the citric acid isn’t required, but it’s what gives commercial versions of this syrup a slightly tart edge instead of tasting like plain sweetened orange. Add blue gel food coloring a couple of drops at a time, stirring as you go, until you reach the bright, saturated blue the flavor is known for. Let cool completely before bottling.

Store the finished syrup in a sealed jar in the fridge for up to 2 weeks. It makes roughly 12 drinks’ worth at 2 tbsp per serving.

This batch (12 servings)$1.07 total

Per 2 tbsp serving~$0.09

Typical store-bought pump bottle (Torani/Monin-style), per serving$0.35-$0.45

Assumptions: sugar at typical grocery pricing, name-brand orange extract (McCormick 2 fl oz bottle, ~$6.49) at small-bottle retail pricing rather than a bulk/warehouse price, a few cents of gel food coloring, and a pinch of citric acid. A store-bought comparison assumes a ~750ml pump bottle around $9-11, yielding about 25 servings at 2 tbsp each.

Storage & Shelf Life

• Keeps about 2 weeks in a sealed jar in the fridge, same as our other sugar-based syrups.
• Give it a shake before using — food coloring can settle slightly, though it’s fully dissolved and won’t separate the way an emulsion would.
• Double the batch if you go through it quickly — everything scales evenly.

Swaps & Notes

• Don’t want artificial food coloring? A natural blue coloring (spirulina-extract-based blue coloring, sold at most grocery stores now) works as a swap — it can read slightly more teal/green than the neon-blue standard, but it’s a genuine option if that matters to you.
• No citric acid on hand? Skip it — the syrup is still good, just a touch sweeter and less bright-tasting than the citric-acid version.
• Want it stronger-flavored? Push the orange extract to 1.5 tsp — taste after adding, since orange extract can turn bitter/medicinal past a certain point.

What to Make With This

2 tbsp of this syrup is what turns a plain soda or energy drink into a “blue” drink — see our Blue Lagoon Energy Cooler for a full build using this exact syrup.

FAQ

Is this the same thing as the blue curaçao liqueur?

No, and this is worth being explicit about: the liqueur is an alcoholic orange-flavored spirit. This syrup has no alcohol at all — it’s a flavoring syrup, the same non-alcoholic category Torani and Monin already sell bottled versions of for coffee shops and home bars alike. The name refers to the flavor profile (bright orange, with the syrup’s signature blue color), not the drink.

Why is the color blue if it’s flavored like orange?

That’s actually true of the original liqueur too — it’s made from the dried peel of the (green-when-ripe) laraha citrus, and the vivid blue color is added dye, not a natural byproduct of the orange flavor. Both the liqueur and every flavoring-syrup version of it are blue by added color, not by anything intrinsic to citrus.

Can I make this without artificial food coloring?

Yes — see the Swaps & Notes above for a natural spirulina-based blue coloring option. It won’t hit quite the same neon shade, but the flavor is identical either way since the color and flavor are separate additions in this recipe.
