Do you have any idea how easy it is to make jam? I had some frozen blackberries from one of many blackberry picking adventures. (I planted three black berries on the hill above the artichokes...oh someday i will have my own patch!) But in the meantime, I have good friends and wild berries to keep me busy.
There are great directions that can be found here for preparing and preserving your own fruit jams. But if it all feels too fussy, there's no reason you can't just do what I do, which is 1) take fresh or frozen-from-fresh blackberries. Around 6 or 8 cups worth. Bring it to a hard boil (meaning, when you stir it, the boiling bubbles don't go down) and add a packet of low-sugar pectin.Let it dissolve, stirring constantly, then add 2 or 3 cups of granulated sugar. Let it dissolve, stirring constantly, then I use a hand masher to mush it all up while it's cooking for another 10 minutes or so.
Then I spooned it into jars and let it cool, jar lids on. Let that sit on the counter. Convince yourself that it will never set, that you'll be left with berry soup at the end of the day. Come back in a couple of hours and be pleasantly surprised that it actually worked, and the jam is, in fact, of jam-like consistency.
So store without bothering to water bath preserve them, I just popped these jars in the refrigerator. They'll stay for a couple of months, good as fresh, but they won't last that long anyway, so it was a good solution. I could also freeze it, pretty much indefinitely.
There are all kinds of snappy ideas about adding lemon (acidity helps it set) or using sugar substitutes (only an option with low-sugar pectin), but don't let that stuff intimidate you. You can just ignore it (I do, and my jam is still fab : )
