It was my first attempt canning solo - no one to ask for help and just an instruction sheet that came with the jars as reference. I think I did okay.
I emptied about 5 quart bags of cherry plums from the freezer into a huge pot to cook down. I wound up with 17 half-pint jars of jam. I think we've got enough to last us a long while even if I give half of it away!
Then there are still 2 quarts bags of cherry plums in the freezer...that was quite a harvest!
