ā“ What is simple syrup?

Simple syrup is a simple one-to-one sugar syrup that is a quick and easy way to add sweetness and flavor to liquids, like your favorite iced coffees or tea drinks.

While the most basic simple syrup is just water and sugar, there are endless flavor possibilities for making syrups your own. We love mixing fruit like our Blueberry Simple Syrup or even making your own Keto Simple Syrup.

In addition to a foundation 1:1 simple syrup, you can also make a rich simple syrup, which is a 2:1 ration of two parts sugar to one part water. A rich simple syrup will not freeze as quickly as a traditional simple syrup.

šŸ§Š How to store simple syrup (refrigerator + freezer)

The best way to keep simple syrups fresh is by storing them in airtight container in the refrigerator. A plain sugar and water syrup can be stored in the refrigerator for up to 2-4 weeks, but a fruit syrup will need to be used in about one week before the simple may go bad.

Simple syrups can also be frozen, which will keep significantly extend the life of the syrup. The best way to freeze simple syrup is to pour it into a silicon ice tray into small cubes and then store in an airtight freezer bag so you can pull out as much or as little as you want when you’re ready to thaw.

šŸ„¶ Tips and tips for freezing simple syrup

While freezing simple syrup is as easy as popping into an ice tray, there are a few tips and tricks to make sure you have tasty syrups every time:

  • What to do if syrup clumps together: If the simple syrup is clumped when you pull it out of the freezer, place the liquid in a glass jar with a lid and warm up in the microwave for 30 seconds. This will allow you to then break the syrup cubes apart and refreeze what you don’t need.
  • How to store different flavored syrups: If you have to store syrups of different types together, label each container or bag with the type of syrup you made and the dates you made them so you know how long they’ve been frozen.
  • How to thaw frozen simple syrup: The best way to thaw your simple syrup is to take it out the night before by taking it out of its freezer bag. You can also put the syrup in a glass container and let it sit at room temperature until you need it, or place the frozen ice trays into a watertight bag under warm water to speed up the thawing process.

ā° How long can you freeze simple syrup?

You can store your simple syrup in the freezer for about 6 months, depending on how often you use it. If you’re not sure how often you’ll use the frozen syrup, keep it in the freezer for shorter periods of time to avoid having a bunch of expired syrup.

šŸ§Š Ways to use simple syrup ice cubes

After the cubes are frozen, they can be thawed and used as regular liquid syrup. But syrup cubes can be used for any of these ways:

  • Add to hot or cold drinks (like coffee or tea) to boost flavor and sweetness.
  • Make popsicles! Pour a bit of water over your flavored sugar cubes in an ice tray, stir to dissolve a bit of the frozen syrup, then add your favorite liquid for a refreshing summer treat.
  • Use as flavored ice cubes or water enhancers at events like weddings and baby showers. Add colored water or food coloring to liquify your simple syrup before freezing to give water a pretty tint (and flavor!).
  • Eliminate the need for a sweetener in recipes by adding them to recipes as needed (in place of sugar). The frozen cubes will melt into your recipe, eliminating the need or measuring how much you need.
