1. Preheat your oven to 170° or the lowest temperature setting you have. Line a baking tray with parchment paper or an oven-safe wire rack.
2. Arrange the citrus slices on the tray grouping the fruit together (limes with limes, etc).

Limes and Lemons

Dehydrate for 4 to 5 hours (or until completely dried) and rotate the baking sheets every 2 hours so that the citrus in the back is now in the front. If you use parchment paper, you will need to flip the citrus every 2 hours.

Oranges

Dehydrate for 6 to 7 hours and rotate the baking sheets every 2 hours so that the citrus in the back is now in the front. If you use parchment paper, you will need to flip the citrus every 2 hours.

Grapefruit

Dehydrate for 8 to 9 hours (or until completely dried) and rotate the baking sheets every 2 hours so that the citrus in the back is now in the front. If you use parchment paper, you will need to flip the citrus every 2 hours.

3. Remove the citrus from the oven and let them cool completely. You can store the citrus in an air-tight container in a dry area.

Dragon Fruit & kiwi

1. Dehydrate for 7 hours on a wire rack lined baking sheet.
