Wash and peel or carefully slice off thin pieces of the lemon skins. Use organic lemons or fresh from the tree.

Layout the skins on a tray and dehydrate using a dehydrator or oven at 45degrees for 2-4 hours until completely dry.

Add the dry peels to a spice blender, food processor, or Nutribullet and blitz to a fine powder.

Place in a jar. I save my spice jars to recycle for future homemade spices such as this.
