Making blackberry jam, or any jam, is about the easiest canning project there is.
Step 1. Cook down 7 quarts of blackberries.
Step 2. When berries come a boil, add 2 packets of liquid pectin.
Step 3. Bring it back to a boil and add 7 cups of sugar. We use Turbinado (raw sugar).
Bring just to a boil, skim off the top and pour into jars leaving 1/2 inch headspace.
Wipe off rims of jars and put the lids on.
Bring water to a boil in the canner, insert jars and add more hot water if necessary to cover jars by at least 1 to 2 inches. Bring water back to a boil before timing. Time 5 minutes for pints and 10 minutes for quarts.
To remove seeds from blackberries, put your berries through a food mill before cooking them down.
Most jam recipes recommend that you do not make big batches at a time because they may not set. I have been successful with this large recipe so far. It makes about 14 pints. In this case I didn't have 14 pint jars available so there are some quarts and 1/2 pint jelly jars included too. Talk about delicious!! We have blackberry jam from the garden to enjoy till next years harvest with lots to share!!
What a great blog and thanks so much for the wonderful images and jam recipe. I will try it next week. Thanks again.
ReplyDeleteHello Heidi! Thank you for stopping by and good luck with your jam!
ReplyDeleteI need to pull the blackberries out of the freezer from last year and get this done. our blackberries around here didn't do very well this year. not sure why. I thought they loved this type of heat!
ReplyDeleteHey Monica, that's what I did, just to free up some freezer space. The blackberries did so well last year, I still have enough to make at least 4 more batches, but what would I do with all that jam?
ReplyDeleteIt has been so hot here this year that the blackberries in our area have really suffered. We planted two more bushes, but not in full sun this time. That late afternoon sun seems to be what is hurting them.
What does it mean when it says Bring water to a boil in camber and insert jars? Do u bring water to a boil in a large pot and put each closed mason jar of the just poured Jam mix into that boiling water? I'm confused
ReplyDeleteUsing a hot water bath canner, bring your water to a boil. Use enough water to cover your jars by about one inch. Fill your jars with the jam, leaving 1/2 inch headspace. Make sure the rims are clean before putting on the lids. Carefully place the jars into the boiling water. Let the water return to a boiling state before timing your processing time. 5 minutes for pints, 10 minutes for quarts. I hope this helps!
