I know how addictive it is. I picked some blackberries on a camping trip summer before last. It was just enough for a batch, but I was still scared of canning, so I made freezer jam. Yum! So last year I made jam from everything that was free or about to go bad. I made plum (from italian prune-plums), apricot (from an abandoned apricot tree), Pear, and blackberry. I only made about 4 of the plum because I wasn't sure it would be good, but that was the best kind! I had to re-cook it (too runny), so I made it into freezer jam. For some reason, I don't get into it much.
I still have alot, and will probably make more this year. I think people are getting plum and apricot jam for christmas this year. Something happened with my pectin, and nothing set right. But I found I really like it that way. Doesn't hurt the sandwiches and I kinda like being able to pour it onto the bread for pb sandwiches. I'm going to forgo the pectin this year and just cook it down more.
