Crock Pot Blackberry Jam

We spent the past couple weeks picking fresh ripe blackberries from the abundance of blackberry bushes in our neighborhood. I think we filled up at least 5-6 containers like these!

So what was I going to do with all of our blackberries? I knew I had to make jam! Crock Pot jam of course! I found an easy recipe HERE and with a lot of help and mentoring from my friend Heather at Fruitful Delights, I made 3 batches and canned 20 jars!
Here is the recipe and feel free use these recipe cards I made (download the printable recipe cards HERE).
Lightly mash blackberries in a bowl with a potato masher. They should be chunky.
Transfer to crock pot and add in the sugar and lemon juice. 
Cook on low for 2.5 hours, stirring twice. Remove lid and cook on high for 2-3 hours. 
The jam will look thin but it will thicken once it cools. 

My first batch came out too liquidy so I e-mailed Heather from Fruitful Delights and she suggest I add one more cup of sugar and another tablespoon of lemon juice and cook for one more hour. And it came out PERFECT!! Thanks Heather!
I canned my jars which should last about 6 months since this recipe does not have any pectin or preservatives in it. Otherwise you can leave it in your refrigerator for  up to 2 months.
If you aren’t a fan of the seeds, you can strain your jam once it has cooked. I did one batch like this using a jelly strainer I found at the Culinary Apple in Lake Chelan, WA. Again, it will thicken once it has completely cooled. 
This jam is not like store bought jam (it is BETTER!). It is homemade and will not have the same consistency as store jams. The pictures above should give you a good idea of what it should look like when spread on toast. I had 3 taste testers who gave it raving reviews! This would also make a great gift. I gave some to our new neighbors! I found these cute new neighbor tags HERE. I think they work well if you have a new family in the neighborhood or you just moved in and want to get to know your neighbors.

    I love blackberries and your jam looks delicious, and doing it in the crock pot is even better!! Love the tags, too! :) We just picked an abundance of blackberries recently and made cupcakes with blackberry icing as well as an apple/blackberry crumble!! YUM!

    Thank you so much for linking up your wonderful looking Blackberry jam to Creative Thursday last week. I can see me making this for the holidays and starting now so I can eat this yummy jam in the morning with my toast! I can’t wait to see what you link up this week. I wouldn’t be able to do these wonderful parties without your participation. Have a wonderful week.
