Thanks judydawn.  I gave my mum some of my "citrus spread" as I am now calling it and still have another jar in the fridge.  Next time I will look into sterilising the jars so I can keep them in the pantry.  I really like the idea that all the fruit is used as all the fibre must help make up for the sugar surely? Lol.

I made this jam after having a quick look for a cordial recipe that lead me here.  I was skeptical after reading some of the comments but had nothing to lose.  Well it turned out just great.  It has a good gelling consistency and the flavour is really yummy, like a marmalade. 
I made lemon cordial but for this jam I used the pulp from a cordial made up of one ruby red grapefruit, two oranges, four mandarins and one lemon.  I peeled the skin off the grapefruit which I used but I cut away the pith as I thought it would be too much.
I wouldn't make this jam with just the lemon pulp as I can imagine that would be too bitter but the mixed citrus is a winner.  I am really chuffed as previous jam attempts have been a bit runny.  And this is a great bonus recipe - using stuff that would normally go in the bin!  I actually froze some excess pulp as I didn't have enough sugar so will try using that one day.
Thanks for a great recipe or should I say two recipes!
