Damson and apple jam - help please

I have never heard of damson and apple jam, although I have made both seperately. For damson it is the same as greengages and plums. Chop them up and stone, simmer in pan, with just enough water to cover, until like a puree. Then weigh (you need to have already weighed the empty pan). Add same weight of sugar as fruit. Bring to boil, test for set, add nut of butter to clarify, pot and cover.

Sorry, that should read 'add same weight of sugar as remaining fruit+water.' It is important to weigh after boiling and stone removal.

Does it work to liquid measure rather than weigh? i.e. measure the pulp with a jug and add the same quantity of sugar that way?

Yes Baggy, it does, but measuring with a jug means you always lose some, whereas if you weigh the pan, you do not need any utensils and therefore no wasted drips or a coating left on the jug. Every drop is precious!

The damson half should set well without pectin too, as jam made from any of the plum family sets without a problem.

Good thinking, granny23! I'm always glad of don't waste anything ideas!

I think most jam is same amount of sugar as fruit.

In my old Mrs Beeton's plum and apple is 1 and a half lbs plums, same of apples, 3 lbs sugar, three quarters pint water.

Just simmer fruit with water till tender, add warmed sugar stir till its all dissolved, then rolling boil till setting point reached. I would test on cold saucer after 10 minutes.

Thank you every one. That is very helpful. I have spent the day rounding up empty jam jars and will make it tomorrow with my DGC. All this is due to the fact that my DD is expecting her third baby in three weeks, and she is nesting, but delegating her nesting desires. I am gathering fruit and making jam, her DH is decorating their bedroom as we speak, and my DH is laying their new lounge floor and putting in new skirting boards........!!!

Jam made, and it is delicious. Always scares me when I see just how much sugar goes in. Did cut it back a bit though. Have made 17 jars and it works out at less than 25p a jar - bargain. My DGD loved decorating the labels as well.
