Here you go. Seems the recipe wasn't a huge success but Jo does say that the peel can be candied etc so now to hunt out Andies recipe
RosieB, I have a recipe on here and on my blog for candied peel. Working on iPad so can't link.
Here's one link for preserving it as you would lemons (or sour oranges) for middle eastern meals.If you scroll down on this page in my blog you will see my process of candying peel in the microwave, which is great when you have a small amount of peel.
I scanned through a list of ideas for "unusual citrus" and found this link for something different.Of course, one does have to enjoy alcoholic beverages!
