Drying Citrus Slices
Drying citrus is a matter of patience and low heat, transforming fruit into brittle, translucent medallions. By dehydrating thin slices in a low-temperature oven, you remove the moisture content while locking in the zest and natural color, creating a garnish that holds its structure indefinitely.
Uniformity is the only metric that matters.
If your slices vary in thickness, the thin ones will burn while the thick ones remain soft and prone to mold. Use a mandoline if you have one.

- Wire cooling rack
What goes in.

Evaporation over cooking
Keep the oven door cracked to allow moisture to escape; otherwise, the fruit will steam rather than dehydrate.
The method.
Prep the fruit
Scrub the skins well and pat them dry. Slice the citrus into rounds exactly 1/8-inch thick. Discard the end caps.
Arrange the slices
Lay the slices on a wire rack set inside your baking sheet. This allows air to circulate underneath, preventing the bottom from becoming gummy.
Set the oven
Preheat your oven to its lowest possible setting, usually between 170°F and 200°F.
Dehydrate
Place the tray in the oven and wedge the door open with the handle of a wooden spoon. Bake for 4 to 6 hours, flipping the slices halfway through.
Cool and store
The fruit is finished when it feels stiff and leather-like, with no soft spots in the center. Let them cool completely on the rack before moving to a glass jar.
When it doesn't go to plan.
Choose fruit with thin, tight skin for the best appearance.
If the center of a slice feels cool or damp to the touch, it needs more time; do not rush this or the batch will spoil.
Store in a cool, dark cupboard in an airtight container to maintain the vibrant color.
The ones that keep coming up.
Why do my slices turn brown?
The oven temperature is likely too high, causing the natural sugars to caramelize rather than simply drying. Stick to the lowest setting.
How long do these keep?
If completely dried, they will stay stable for several months, though the color will fade slightly over time.
