Preserving Sunshine: A Guide to Drying Citrus Zest

The scent of citrus zest always transports me back to my grandmother’s kitchen. I remember standing on a wobbly stool, diligently grating lemons while she hummed a cheerful tune. The air would be thick with the bright, tangy aroma, a promise of the delicious lemon bars or meringue pies to come. That simple act, transforming a humble fruit peel into a burst of flavor, sparked a lifelong fascination with the power of citrus – and a determination to never let a single zest-able peel go to waste!

Equipment Needed

• Microplane or zester
• Plate or waxed paper
• Airtight jar or container

Instructions

1. Begin by selecting your citrus fruit. If possible, opt for organic varieties. If using non-organic fruit, thoroughly wash and dry the citrus under cool running water. This is essential to remove any potential surface residues. Remember, we’re after pure, unadulterated citrus flavor. I listed 4 fruits, but would zest, dry and store separately.
2. Using a microplane or zester, carefully draw the zest across the surface of the fruit. The key is to only remove the colored part of the peel – the zest – and avoid the white, bitter pith underneath. Apply gentle, even pressure and work your way around the fruit, rotating it as you go.
3. Spread the freshly grated zest in a single layer on a clean plate or a sheet of waxed paper. Ensure there is adequate spacing between the individual pieces of zest to allow for proper air circulation.
4. Leave the zest exposed to the air in a cool, dry place. The drying time will vary depending on the humidity and temperature of your environment, but it typically takes 2 to 3 days until the zest is dry enough to be brittle. You can also put them in a dehydrator for a quicker result
5. To test for doneness, take a small pinch of zest and crumble it between your fingers. If it snaps easily and feels completely dry, it’s ready. If it’s still pliable or slightly damp, allow it to dry for a little longer.
6. Once the zest is completely dry, transfer it to an airtight jar or container. Store it in a cool, dry place away from direct sunlight. Properly dried and stored zest can last for several months while retaining its vibrant flavor.
7. Remember to zest your citrus before cutting into the fruit. It’s simply easier to handle and far less messy. I’ve made it a habit to zest citrus fruit before juicing it, so I always have a supply of dried zest on hand.
8. Before adding the dried zest to your recipes, try rubbing it between your fingertips. This releases the oils and intensifies the citrus aroma.
9. For an alternative process, use the zesting process over waxed paper, fold several times and freeze in a zip locked bag.
10. Take advantage of fruit when it’s highly available and low in price.
11. Be careful while zesting. Tools are sharp.

Expert Tips & Tricks

• Avoid Over-Zesting: Be careful not to grate too deeply and include the bitter white pith. The zest should be thin and brightly colored.
• Speed Up Drying: If you live in a humid environment, you can speed up the drying process by using a very low temperature in your oven (around 170°F or 75°C) or a dehydrator. Spread the zest on a baking sheet lined with parchment paper and check it frequently to prevent burning.
• Maximize Flavor: For the most intense flavor, use freshly dried zest within a few weeks. Over time, the oils will dissipate, and the zest will lose some of its potency.
• Pulse in a Spice Grinder: If you prefer a finer texture, you can pulse the dried zest in a spice grinder or food processor until it reaches the desired consistency.
• Don’t Toss the Leftover Fruit! Once you’ve zested your citrus, don’t let the rest of the fruit go to waste. Juice it for cocktails, marinades, or homemade lemonade.

Serving & Storage Suggestions

Dried citrus zest can be used in a multitude of ways. Add it to tea blends, mulled cider, cakes, pies, oatmeal, cookies, jellies & preserves, or use it in place of extracts. You can also incorporate it into cake frostings, flavored honey & butters, meat rubs, sauces & BBQ sauce. For a thoughtful homemade gift, package dried citrus zest in small, attractive jars.

Store dried citrus zest in an airtight container in a cool, dark, and dry place. When properly stored, it will retain its flavor and aroma for up to 6 months.

FAQs (Frequently Asked Questions)

Q: Can I use a vegetable peeler instead of a microplane?
A: While a vegetable peeler can be used, it’s more difficult to avoid including the bitter pith. A microplane or zester is the preferred tool for this task.

Q: How long does dried citrus zest last?
A: Properly dried and stored citrus zest can last for up to 6 months while retaining its flavor.

Q: My zest is clumping together during drying. What am I doing wrong?
A: Make sure you are spreading the zest in a single layer with adequate spacing between the pieces. Also, ensure that the area where you are drying the zest is not too humid.

Q: Can I use this method for other citrus fruits besides lemon, lime, orange, and grapefruit?
A: Yes, this method works for any citrus fruit, including mandarins, tangerines, and pomelos.

Q: Can I dry the zest in the microwave?
A: While it’s possible, it’s not recommended as it can easily burn the zest. The air-drying or low-oven method is more reliable.
