How to Freeze Zest
If you want to use your zest in desserts or cakes, this is the best approach.
- Grat Zest: First, you’ll need to grate the zest, so get to it. Try to avoid grating any of the white pith, which can be bitter and unpleasant. When it comes to freezing zest, you want to focus on getting the best concentration of citrus flavour you can.
- Bag Up and Freeze: Tip your zest into a freezer bag and place it in the freezer.
When you need some zest, grab some from the bag. You may need to snap it off as it can freeze into a clump depending on the zest’s water content.
You could spread it out on a baking tray, flash freeze and then store it in a bag to avoid clumping – but who’s got time for that!
How to Freeze Zest in Ice Cubes
If you are going to stir your zest into stews, rice dishes, or soups, then use this approach:
- Grate: As you’ve probably guessed, you’ll need to grate your zest again, so get grating.
- Spoon into Ice Cube Tray: Once you’ve got your zest, spoon it into the slots of an ice cube tray. You want to fill each slot around two-thirds of the way.
- Top up with Water: Once filled, top each slot up with water, then wrap the tray in cling film to keep it protected.
- Flash Freeze: Place the tray in the freezer and give the ice cubes several hours to freeze solid.
- Final Freeze: Once frozen, you can pop them out of the tray and into a freezer bag for easier long-term storage.
3 Tips for Freezing Zest
Now you know how to freeze it, we’ve got our 3 top tips which we strongly recommend following when freezing zest to have the best results:
Consider Your Use
Think about how you’re going to use the zest and freeze it accordingly. If you want it for desserts, then freezing it grated into a bag is the best way to go about it. If, however, you want to stir it into stews and soups, then freeze it into ice cubes.
Don’t Forget the Juice
Whatever you do, don’t grate the zest, then throw the rest of the fruit out. You can also freeze the juice from the fruit. Use the ice cube approach above. You could even freeze the zest and juice together!
Try Freeze Whole Fruit
You can freeze whole lemons, limes, and oranges, then grate the zest from the whole fruit directly from the freezer. As you grate it, it will thaw, and you’ll have delicious zest. The only downside is that this can take up more room in the freezer.
How Long Can You Freeze Zest?
Zest will keep for an impressively long time in the freezer.
In fact, you’ll be fine leaving it in the freezer for 6 months. After this time, there is a risk that the flavour will begin to degrade. It will remain completely safe to eat.
Once zest has been taken off the fruit, it will only last for around 1 or 2 days in the fridge. It will very quickly degrade in flavour.
How Do You Defrost Zest?
As the zest is so fine, you don’t need to defrost it. If stirring an ice cube into a cooking pot, then it’ll melt almost instantly.
If you’re using pieces of zest in a cake, then give it a few minutes to soften so that you can break it apart easier and then stir into your dessert or cake batter.
Can You Refreeze Zest?
We would advise against refreezing zest. When you refreeze anything, you draw the moisture out. When you draw the moisture out, you lose some of the flavour. By refreezing zest, you’ll degrade the flavour rapidly.
