I wonder if the massed ranks of yacf marmalade makers may have any ideas ....
Mrs robgul made copious quantities back at the start of the year - using oranges from Waitrose, Aldi and Abel & Cole (veg box people) to a couple of different recipes. All went to plan, it set, loaded ito normal sized jars etc. - made enough to, usually, last the year of toast and marmalade (one slice) for breakfast every day.
BUT when we come to use it the set has gone - it's still perfectly edible but is quite watery/syrupy. Storage is in a cool pantry.
Any thoughts on the reason?
Thanks
Rob
