How to Preserve Citrus Zest by Freezing
Have a recipe that calls for citrus juice, but not the zest? Save it by using this tip, and you'll always have a supply on hand.
A good practice to get in the habit of: always peel the rind off citrus before juicing or using the fruit, and store the rind in a resealable plastic bag in the refrigerator, or even better, preserve citrus zest by storing it in the freezer.
First, to prevent it from being watery once it's thawed, microwave it before freezing for 30 seconds on waxed paper, then let it sit for an hour, or until it's dry. Freeze it in a freezer-safe container. This way, you'll always have zest on hand even if you don’t have the fruit.
