Well, figured I should give some feedback...
I put the chutney back in the pot last night (couldn't on Monday as I was out) and left it to boil for about another hour and a half (basically the time the dishwasher needed to wash the glass jars and lids and then put them into the oven to sterilise)
All in all I emptied 7 jars back into the pot, but when I came to refilling I only filled 5 - so the equivalent of nearly 2 jars that still evaporated / cooked down more (well that's the only thing I can think of) . Admittedly I did fill the jars right to the top this time whereas on Sunday I had the neck of the jar still free - but still; it's a lot less now. But definitely a much much better consistency and the bit that I tasted (licking the spoon at the end
) was really nice so I'm looking forward to it when it's ready in a few months.
I still have a few green cherry toms on the vines so I'll pick all those this Sunday and see how much I get and then do another batch (may as well use the other jars
)
All in all - I'm quite proud of my first attempt ever at preserving anything. Next challenge is jam or something like that
