I very enthusiastically bought 10 kg of seville oranges, and have already made 3 kg of marmalade. Another 3 kgs is getting made today - but then I'm out of jam jars! ::)
I was wondering if I could freeze the oranges somehow, to make the marmelade at a later date.
If so, at what stage of preparation can I freeze them? Obviously I would like to reduce the volume of them first!
