Equipment

Ingredients
  

If you already have a syrup to freeze

  • 16 ounces simple syrup (or however much syrup you have leftover!)

If you need to make a syrup

  • 200 g granulated sugar 1 cup
  • 237 g filtered water 1 cup

Instructions
 

  • Heat water. Pour water into a 1.5-quart saucepan, and place it over medium heat.
    237 g filtered water
  • Add sugar. Add sugar to the pan and stir to dissolve.
    200 g granulated sugar
  • Cool. Once the sugar is completely dissolved, remove the pan from heat and allow it to cool slightly.
  • Pour into container. Transfer the mix to a heat-safe container, like a glass measuring cup, to make it easier to pour into ice cube trays.
  • Portion + freeze. Carefully pour your syrup into ice cube trays, then transfer to the freezer for 6-8 hours, or until frozen.
    16 ounces simple syrup
  • Store. Once the cubes have frozen solid, pop them out of the ice cube tray and store them in a zip-top bag in the freezer for up to 12 months.

Notes

I love using the above-linked ice cube tray from Souper-Cubes because it's marked with measurements, so I know each cube is exactly 1 ounce or 2 TBSP. This makes it super easy to use in drink recipes!

Troubleshooting:

If your syrup doesn't freeze solid, the ratio of sugar to water is higher in your syrup.
Certain heat-infused syrups are more like a rich syrup, which has a 2:1 ratio of sugar to water.
Rich syrups will not freeze solid because of the high sugar content, and they will instead remain sort of gloopy.
