Using a mandolin, slice any type of citrus into thin slices, about 3mm in thickness. (If the citrus is on the sour side, you can sprinkle with a little sugar).

Slice your assorted citrus and use the dehydrating setting on your Air-fryer. Dehydrate for approx 20mins, depending on how dry you would like them, whether dry and crisp of slightly dried but still maleable. Your drying time will be determined by the thickness of your slices amd your desired result.

Uses

Use as a garnish for cakes and puddings.

Citrus slices can add flavour to meat and seafood rubs.
