Boy our blackberries are huge this year. We have gathered 12 or 13 pounds so far, and a few cuts and scrapes from the thorns. The berries are well worth it though. With the first few pounds we made 2 batches of jam. Its something sweet and easy, and you can enjoy the summer harvest, all the way through the winter and until you can make some more next year.
What you need to make the jam is,
1 box of Pectin
5 cups of blackberries
7 cups of sugar
First you need to crush the berries, we sieve about half of the seeds out, you can have more or less seeds depending on your preference. Put
the 5 cups of berries into a stock pot along with the box of pectin, and bring it to a full rolling boil, once it has reached that point, pour in the sugar, and bring it back up to a rolling boil, and boil for 1 minute. That's it for the jam! See, so easy! Now you just ladle it into your sterilized jars, and process the jam for 10 minutes in a water bath canner.
Here is the video we made showing the whole process from start to finish. Sorry for the long video, I just didn't want to edit any important information out of it, that you all might need. Anyway enjoy our video, hope it is helpful!
We're not sure what we will do with the rest of the blackberries we pick, make some more jam probably, then eat the rest :) yum
