• Fiber
• Antioxidants
• Essential oils

The concentrated nature of dried fruit means that a small amount can provide a significant nutritional boost. Additionally, the absence of added sugars or preservatives in home-dehydrated citrus makes it a healthy alternative to commercially processed dried fruits.

Dried citrus also serves as a low-calorie flavoring option, allowing you to enhance the taste of dishes without adding significant calories or artificial ingredients.

Types of Citrus for Dehydration

Various citrus fruits can be dehydrated in the oven to create flavorful, versatile dried citrus wheels. The process works well for lemons, limes, oranges, and grapefruits, each offering unique flavors and uses.

Selecting Citrus Fruits

Lemons and limes are popular choices for dehydration due to their intense flavors and versatility. Navel oranges and blood oranges provide sweetness and vibrant colors when dried. Grapefruits offer a tangy-sweet option with larger slices.

Choose firm, ripe fruits without blemishes or soft spots. Organic citrus is ideal to avoid pesticide residues. Thinner-skinned varieties tend to dry more evenly and quickly.

Preparatory Techniques

Wash and dry the citrus fruits thoroughly before slicing. A mandoline slicer ensures uniform thickness, typically 1/4 inch or less, for even drying.

Remove any seeds from the slices. Some prefer to remove the white pith from oranges and grapefruits to reduce bitterness.

Arrange citrus wheels in a single layer on parchment-lined baking sheets. Avoid overlapping to ensure proper air circulation during the drying process.

For added flavor, sprinkle slices lightly with sugar or brush with honey before dehydrating. This step is optional but can enhance sweetness and create a slight glaze.

Pre-Dehydration Steps

Proper preparation is crucial for successful citrus dehydration. This involves thoroughly cleaning the fruit and cutting it into uniform slices. Setting up the dehydration tray correctly ensures even drying and prevents sticking.

Washing and Slicing

Start by washing the citrus fruits under cool running water. Gently scrub the peels to remove any dirt, wax, or pesticide residues. Pat the fruits dry with a clean towel.

Use a sharp knife or mandoline slicer to cut the citrus into thin, uniform slices. Aim for slices between 1/8 to 1/4 inch thick. Consistent thickness ensures even drying.

Remove any seeds from the slices. For lemons and limes, leave the rind intact. For oranges and grapefruits, you may choose to remove the bitter white pith.

Preparing the Dehydration Tray

Line a baking sheet with parchment paper or a silicone mat. This prevents the citrus slices from sticking to the tray during dehydration.

Arrange the citrus slices in a single layer on the prepared tray. Ensure the slices do not overlap to allow for proper air circulation.

Leave small gaps between each slice. This spacing promotes even drying and prevents the slices from sticking together.

For multiple trays, consider rotating their positions in the oven during dehydration to ensure uniform heat exposure.

Dehydrating Citrus in an Oven

Dehydrating citrus in an oven is a simple process that requires careful temperature control, monitoring, and proper storage. This method produces flavorful dried citrus slices perfect for various culinary and decorative uses.

Setting the Correct Temperature

Set your oven to the lowest possible temperature, typically between 160°F to 200°F (70°C to 95°C). Lower temperatures preserve more nutrients and flavor while preventing burnt edges.

Use the convection setting if available, as it promotes even air circulation. Place a wooden spoon in the oven door to keep it slightly ajar, allowing moisture to escape.

Line baking sheets with parchment paper to prevent sticking. Arrange citrus slices in a single layer, ensuring they don’t overlap.

Timing and Monitoring Process

The drying process usually takes 3 to 6 hours, depending on citrus thickness and oven temperature. Check the slices every 30 minutes, rotating trays for even drying.

Citrus slices are ready when they feel dry to the touch and slightly leathery. They should bend without breaking and have no visible moisture.

For oven-dried orange slices, expect a longer drying time due to their higher water content compared to lemons or limes.

After Dehydration Care

Allow the dried citrus slices to cool completely at room temperature. This step prevents condensation, which could lead to mold growth.

Store the cooled slices in an airtight container. Glass jars or resealable plastic bags work well for this purpose.

Keep the container in a cool, dark place to maintain color and flavor. Properly stored, dried citrus can last up to a year.

For long-term storage, consider adding a food-safe desiccant packet to the container to absorb any residual moisture.

Alternative Dehydrating Methods
