Equipment & Prep

The Anatomy of Citrus Fruits

There are three parts to a citrus fruit: the zest, the pith, and the flesh.

Prepping Your Citrus Fruits (Cleaning)

First, we’ll soak the citrus pieces in a 50/50 vinegar and water solution. This step is essential as it ensures the cleanliness of the fruits and removes any dirt and bacteria.

Trust me, you’ll want to be generous with the vinegar, as we’ll be using the entire fruit. 

Cutting Techniques

Now, let’s talk about cutting the citrus. I recommend using a sharp serrated bread knife or a mandolin, which will make slicing easier because it easily cuts through the citrus skin.

Here is breakdown of various citrus fruits  slicing techniques:

Dehydrating Your Citrus Fruits

Now that your citrus fruits are sliced, it’s time to place them on your dehydrator trays. Arrange the fruit evenly across the trays. You can use a mesh screen, parchment paper, or a tray mat to prevent sticking.

Remember that taste is crucial – if the fruit tastes off before dehydrating, it’ll taste off after as well, so remember to taste your fruit before drying it, as the flavors will intensify during dehydration. If it tastes bad going in, it’ll likely taste bad coming out. 

The same goes for bitterness: if the fruit is bitter, to begin with, expect that bitterness to be even more pronounced once it’s dried.

Dehydration Duration and Temperature

Dehydrate your citrus fruits at 125°F or lower for 18 to 36 hours. The duration depends on your machine, local weather, and slice thickness. Avoid higher temperatures, as they can cause browning.

Once the dehydrating process is complete, you’ll be left with a beautiful array of dried citrus slices. Not only do they make for stunning food art, but they also serve as a fantastic way to use up excess fruit and minimize waste in your home.

Tips and Tricks for Dehydrating Citrus and Repurposing Peelings

Making DIY Citrus Vinegar Cleaner

Don’t throw away those citrus peelings! Instead, turn them into a homemade citrus cleaner by placing the peels in a jar, covering them with vinegar, and letting them steep for two weeks to create a natural cleaner.

This cleaner is perfect for sprucing up your kitchen and bathroom.


To dehydrate just the zest, you can zest a lot of fruit before drying the insides. For an easier way, use a microplane zester to create little shavings of zest.

Avoid drying them in a dehydrator as they will blow around.

Instead, place them in a bowl, cover them with something, and allow them to dry on their own. You can also use a peeler or a box grater, but be careful not to get too far into the pith as it can be extremely bitter.


Some people like to dehydrate segments by slicing the fruit, removing the rind, and eating the insides when dry. To make the drying process more efficient, make slices in the membrane to allow moisture to escape.

Alternatively, you can remove the membrane by hand or use a pectic enzyme to eat it away. You can also cut the segments in half to make them thinner and dry faster.


Properly dehydrated citrus can last up to a year or more. To store, use airtight containers like glass jars or resealable plastic bags. Label them and store them in a cool, dry place away from sunlight.
