The Mad Scientist experiments with drying oranges ...

This was the first experiment with oranges. It worked, with a nice zesty focused flavour, but eating the slices was a bit problematic in that you either had to eat the rind (bitter) or tear the rind open to get at the fruit. The second attempt (not pictured here) involved removing the skin first and then slicing the oranges horizontally in the same fashion. This worked much better.

It also works to split the oranges (or mandarins) into segments and dry them laid out individually on the rack.
