Sharing is caring!

Do you have some delicious fresh blackberries? You have to give this homemade blackberry jam recipe a try!

I am proud to announce that after a good decade of recipe testing, our jam recipe is finally ready to be shared! This has been a labor of love every single summer. Most of the time, met with a lot of disappointment. There is always so much pride and joy when you get a recipe right.

The secret to this homemade blackberry jam recipe? Is freshly picked berries. My husband recently found a patch of wild blackberries and went wild picking them. He was on a mission to to get this blackberry jam right.

Another secret? You have to follow the directions. Many times, we have tried to halve the recipe or even double it. It never comes out right!

Making homemade blackberry jam is the perfect activity to do on one of those random rainy summer days. And I assure you, it’s not nearly as hard as you think it is!

When you crush the blackberries, you will end up with slightly more juice than needed to make the jam. So, I highly recommend making my Blackberry Lemonade recipe with the leftovers!

Do you have some delicious fresh blackberries? You have to give this homemade blackberry jam recipe a try! 

Ingredients

  • 8 cups blackberries
  • 6 1/2 cups sugar
  • 1 pkg Sure-Jell Premium Fruit Pectin
  • 1/2 tsp butter

Instructions

    1. Prepare lids and jars. 
    2. In a stockpot, crush 8 cups of blackberries over medium heat using a potato masher. 
    3. Press the crushed fruit through a small mesh strainer or cheese cloth to remove seeds. 
    4. Measure 6 1/2 cups of sugar into a separate bowl. 
    5. Measure 5 cups of crushed blackberries into a large saucepan. 
    6. Stir in Sure-Jell pectin into fruit. Stir in butter (this reduces foaming). 
    7. Bring mix to a rolling boil on high heat. Stir constantly. 
    8. Add sugar to fruit mixture. Bring back to a rolling boil. Boil for 1 minute. 
    9. Remove from heat. Remove any foam. 
    10. Ladle your homemade blackberry jam right away into your prepared jars. Fill them within a 1/2 inch to the top.
    11. Cover with lids. 
    12. Place jars into boiling water. Be sure to cover jars by 1-2 inches. Add more boiling water if needed. Cover.
    13. Boil your homemade blackberry jam jars for 10 minutes. 
    14. Remove the jars and place on a towel to cool. When cooled, press the center of the jars. If they spring back to you then you will need to refrigerate your jam since it did not process properly. 
    15. Let your homemade blackberry jam stand for 24 hours and then store in a cool, dry place.

Can you use frozen blackberries

Yes you can use frozen blackberries, but they should be defrosted and drained first b/c otherwise there will be too much liquid and your blackberry jam will not work.

How much does this make? It does not show a yield of the size containers used or how many containers or ounces it makes.

Hi Ashley, Thanks for your question! It really varies everytime we make this. We use the 16oz mason jars and usually use an entire case of jars (dozen). I would have a few more on hand though just in case.
