Blimey - I had a look at the results in Google. I particularly liked the look of this recipe
as it makes a small amount so you can try the method out.
Perhaps thats why I thought it unfeasible to use a Microwave - I usually make 8lbs at a time which is a huge panful.
A top tip is buy a years supply of seville oranges when available (Jan/Feb in UK) and freeze them so you can make fresh batches as the year progresses.
