Ingredients

Find the simple ingredients for this blue Curacao syrup recipe in the printable recipe card at the bottom of this post. Here is a rundown of what you will need.

  • Orange. The taste of blue Curacao has an orange taste. It’s made traditionally from the Lahara citrus, which is a descendant of the orange. It’s a very bitter fruit. In this syrup we are using the orange peel including the pith, to infuse the orange flavor and a little bitternessIinto the syrup.
  • White sugar. Granulated cane sugar. You could use raw sugar, or pure cane sugar but avoid light brown sugar, which will change the flavor. The amount of sugar is large but remember, it’s syrup and meant to be sweet.
  • Water
  • Citric acid or lemon juice. Some citric acid or lemon juice enhances the orange flavor and helps balance the sweetness. You could use lime juice too.

See the recipe card for quantities.

A simple syrup

The sugar-to-water ratio in simple syrup equal parts water and sugar. 

This is often measured in volume – 1 cup of sugar with 1 cup water. Volume is less consistent than measuring in weight (there is 40g more water than sugar in a cup), but it doesn’t make much difference in a recipe like this.

Equipment

  • Small saucepan
  • Muslin cloth
  • Glass bowl
  • Glass jar

Instructions

To make the blue Curacao syrup, peel the skin off the orange using a vegetable peeler or sharp knife. The orange pith should be included to bring in some bitterness.
