Equipment

  • spice grinder
  • Dehydrator or oven
  • orange peeler

Ingredients

  • 2 large navel oranges (or any variety with a thick rind)

Instructions

  • Select organic oranges that are free of bruises and blemishes.
  • Wash the fruit VERY thoroughly to remove dirt, debris, germs, agricultural sprays, and other possible contaminants.
  • Peel the fruit, retaining as much of the pith as possible on the peel.
  • Slice peels into thin, equal strips.
  • Dry the peels using whatever option you like (see various directions below for options). I prefer the dehydrator.
  • The peels are fully dried and ready to grind when they snap and break when bent.
  • When the peels are completely dry, place in a spice grinder or blender and pulverize them into a fine powder.
  • Store in an air-tight container (a mason jar works great for this) in a cool, dark place for up to three months or in the freezer for up to six months.

Dehydrating

  • Place peels in a dehydrator at 115ºF for 4-6 hours. The time will vary depending on the thickness of the peel and size of the pieces, humidity level, and of course will change with a different temperature.

Oven Drying

  • Place peels baking sheet and set in a warm oven set on the lowest temperature available. At approximately 150F, the peels will dry in 1 – 1 1/2 hours, again depending on the thickness and size of the slices. When dry, remove from the oven and let cool.

Air Drying

  • Place the peels on one layer on a plate or tray. Dehydrator trays work great for this.
  • Let the peels dry for 3-4 days.

Notes

- Organic fruit: Organic is a must since insecticide and pesticide residues are typically applied multiple applications throughout the growing season. In one study, 95% of samples had pesticides on them. I have read that these chemicals can penetrate into the peel of citrus fruits (and so they cannot be washed off), and while that does make sense, I don't know if that's true or not.
The best way to dry: I think dehydrating is the best way to dry the peels, since you don't need to turn your oven on, and air drying can be very complicated (needing to prevent pests from having access, etc.) and difficult in more humid climates.
Any Citrus Works: Any type of citrus peels will work for this recipe--lemon, lime, and grapefruit or pumelo are all great options.
