Take a small pot and bring water and sugar to a boil.  Cut the lime into thin slices. Place the slices in the sugar syrup and let it boil for 3 minutes.  Remove the pot from the heat and let it steep for 10 minutes.  Now take the lime slices out of the sugar syrup and let them cool on a piece of baking paper.  Then place the lime slices on a tray in the dehydrator.  Dry/dehydrate the lime slices for 8 hours.
