Preparing the Citrus

Choose Your Fruits

Start by giving your citrus fruits a thorough wash, preferably using organic ones. We’ll be using the peel, so cleanliness is key. For this recipe, I used a lime, lemon, blood orange, and navel orange.

Perfect Slices

Next, slice your fruits as thinly as possible, aiming for about 2 millimeters in thickness. A mandolin can be helpful here. The thinner the slices, the quicker they’ll dehydrate.

Seed Removal

Once you’ve cut your fruits, remove any remaining seeds from the slices.

Adding That Sweet Touch

Sugar Prep

Pour some sugar into a small dish.

Arrange and Coat

Orange Slices Covered In Sugar

Line a baking tray with a non-stick silicone mat or parchment paper. Lightly coat the citrus slices in sugar and arrange them on the prepared tray. If you’d like to dehydrate without candying, simply skip this step.

Drying Process

Initial Baking

Cover the citrus slices with another silicone mat or parchment paper, and place another baking tray on top to weigh it down. Pop the tray into a preheated oven at 250°F (120°C) for 15 minutes.

Adjust and Dry

After 15 minutes, take the tray out of the oven and remove the top tray and silicone mat. Pat the slices dry with a paper towel. The peel and rind should start to become translucent.

Lower the oven temperature to 175°F (79°C) and return the tray for 2 to 2.5 hours, depending on the thickness and size of the slices.

Size Matters

When the fruits feel dry to the touch, remove them from the oven.

If you’re using different citrus types in one tray, you might need to take out smaller slices first.

Cooling and Enjoying

Cool and Harden

Carefully transfer the citrus slices from the mat to a wire rack to cool. They’ll be somewhat flexible while warm but will harden as they cool down.

Final Touches

For my recipe, I removed the lemon and lime slices first and returned the oranges to the oven for an extra 30 minutes.
