Drying Orange Zest
Drying is one of the simplest and most effective ways to preserve orange zest. The process involves removing the moisture from the zest, making it possible to store it for an extended period. Here are a few methods to dry orange zest:
Oven Drying
Oven drying is a quick and easy method to dry orange zest. Simply place the zest on a baking sheet lined with parchment paper and dry in a low oven (150°F – 200°F) for 1-2 hours. Check on the zest every 30 minutes to ensure it doesn’t overdry.
Dehydrator Drying
A dehydrator is a great investment for any serious home cook. Simply place the zest on the dehydrator trays and set the temperature to 135°F – 150°F. The dehydrator will do the rest, slowly removing the moisture from the zest.
Air Drying
Air drying is a low-tech method that requires patience. Place the zest on a paper towel-lined plate or tray and let it sit in a single layer. Cover with another paper towel and let it air dry for 2-3 days. Stir the zest occasionally to ensure even drying.

Freezing is another excellent way to preserve orange zest. Frozen orange zest can be used in both sweet and savory dishes, adding a burst of citrus flavor. To freeze orange zest:

Grate the orange zest and mix with a small amount of water to create a paste. Spoon the paste into ice cube trays and freeze. Once frozen, transfer the zest cubes to an airtight container or freezer bag, and store in the freezer for up to 6 months.
