How Do You Dehydrate Lemons and Limes?

You can dehydrate lemons and limes using a dehydrator or a low-temperature oven.

Dehydrating Lemons and Limes

Here's a breakdown of how to dehydrate lemons and limes using either a dehydrator or an oven:

Wash the Fruit: Thoroughly wash lemons and limes to remove any dirt, wax, or pesticides. You can use a fruit and vegetable wash or a solution of water and vinegar.
Slice the Fruit: Slice the lemons and limes into approximately ¼-inch thick slices. Consistent thickness ensures even drying. You can use a sharp knife or a mandoline slicer for uniform slices.
Optional: Remove Seeds: Remove any visible seeds to prevent bitterness.

Arrange Slices: Lay the lemon and lime slices on the dehydrator trays in a single layer, ensuring they do not touch. This allows for proper air circulation.
Set Temperature: If your dehydrator has temperature settings, set it to 135°F (57°C) or a "medium-high" setting.
Dehydrate: Dehydrate for approximately 6-12 hours, or until the slices are brittle and no longer sticky. The exact time will depend on the thickness of the slices and the humidity. Check frequently after 6 hours.

Preheat Oven: Preheat your oven to the lowest possible temperature, ideally around 170-200°F (77-93°C). A convection oven is preferable because it circulates air more efficiently, but a standard oven will work.
Arrange Slices: Place wire racks on baking sheets. Arrange the lemon and lime slices on the racks in a single layer, ensuring they don't touch. The racks allow for air circulation around the slices.
Dehydrate: Place the baking sheets in the oven and prop the oven door slightly open to allow moisture to escape. Dehydrate for approximately 2-4 hours, or until the slices are brittle and dry. Check frequently to prevent burning. Rotate the pans every hour for even drying.

The lemon and lime slices should be brittle and translucent when fully dehydrated. They should snap easily when bent. If they are still pliable or sticky, continue dehydrating.

Once the lemon and lime slices are completely cool, store them in an airtight container in a cool, dark, and dry place. Properly dehydrated and stored citrus can last for several months.
