Blackberries are the only fruit that I prefer to deseed. The seeds are so large in blackberries, in comparison to raspberries! I freeze the juice until the weather cools down because it is so hot when we pick them, I can’t bare to turn on the canning pot to fight with air conditioner! It seems like a waste of energy.

I promise, this is last jam recipe I will do this year! In my defense though, a lot of you are looking at all of my jam recipes, all year long, so I don’t feel too bad! 🙂

We have about 2 acres on our property that has wild blackberries growing on them. We rather nurture them a bit, because we so love the fruits of our labor. Eric and I have been picking them for years, so we are pretty careful picking them. The issue is not putting your hand in to reach a huge, plump blackberry, the danger is in pulling your hand back out! The thorns are angled so that the extraction is the dangerous part.

A few years ago, when my in-laws started staying with us for the summer, in their motor home. My Father-in-law and our neighbor across the street had this competition going, I swear, like, who could get the biggest berry. The biggest berry is inevitably in the middle of the patch! The competition ended up being, who could get their arms and legs more scratched up by blackberries! They both looked like they had been through a war! 😂 Deep, painful gashes for weeks! Heros I tell ya, all for the elusive biggest berry!

How to make this Low Sugar Blackberry Jam Recipe

  1. Use Kitchenaid Juicer attachment to deseed blackberries, if desired. Alternately, the juice can be squeezed through cheesecloth or a strainer but it is no fun.

    2. I did it for years, even though I had a Kitchenaid Juicer in the closet. “Why?” you ask. Because, dear reader, until my friend Laura, with her “Canning tomato sauce in my Kitchen” post reminded that I had one, I did not think about that! Um, what?

Add the juice with water to a large pot. Mix the pectin with 1/4 c. sugar, to help the pectin mot to clump. Add to the pot with the juice. When it comes to a full rolling boil (one that can’t be stirred down), add the rest of the sugar all at once. Again, bring the mixture to a full rolling boil and continue to boil hard for at least 1 full minute. Immediately ladle into hot sterilized jars. Put on lids and hand tighten rings. (Not too tight!) Place jars in a water bath canning pot and process for 10 minutes. Adjust for altitude, here is a great graph! Let jars rest in canning pot an additional 5 minutes. After the rest remove the jars from the canning pot and let cool on the counter for 24 hours. After a short amount of time you will here the lids “pop” that is always a good thing because that means that they have sealed.
Check the lids after the 24 hours. Any lids that snap in the middle have not sealed properly and should be refrigerated. The sealed jars are best stored in a cool, dark place, like a basement.

Ingredients
  • 1 1/3 cups prepared blackberry juice
  • 1/3 cup Unsweetened Fruit Juice , thawed frozen juice concentrate or water
  • 1 1/2 tbsp Low Sugar Pectin
  • 1/2 cup up to 1/2 Cup sugar, sugar substitute or honey
Instructions

  1. Juice blackberries, either with this attachment for your kitchen aid, using a food mill or other juicer, or by hand. The easiest way to juice them by hand is to let them cook down for about 15 minutes in a a bit of water. Then run the juice through a sieve lined with cheesecloth. Juice can be frozen for later use.


  2. Prepare jars. Wash in hot soapy water and rinse thoroughly. Place directly in water bath canning pot. Cover clean jars with water about 2 inches above jars. Boil jars for 10 – 15 minutes to sterilize. Let jars sit in hot water until ready to fill.

  3. Place washed lids in a small saucepan and cover with boiling water. Let sit until ready to use. I also add my ladle and funnel to this pot to sterilize them.

  4. Add juice and water to a large, heavy bottom pot. Heat over high heat.

  5. Meanwhile, mix pectin with 1/4 cup of sugar to keep the pectin from clumping, Add the mixture to the pot. Stir constantly, after pectin is added.

  6. Bring plums to a boil and add pectin/ sugar mixture. Bring to a full boil (one that can’t be stirred down).

  7. Add the rest of sugar all at once. Again, bring to a full boil and boil for 1 full minute

  8. Fill jars, leaving 1/2" headspace. Wipe rim of jars with clean paper towel and place lid on. Add band and tighten to fingertip tight.

  9. Place filled jars into canning pot and bring to boil. Low boil for 10 minutes.

  10. Turn off heat and allow to sit in water for 5 minutes. Remove them to counter and let them cool.

  11. After 24 hours, check lids by pushing down in center. If lids flex up and down, the jar is not sealed and should be refrigerated.


  12. Jars that have sealed should be stored in a cool place for a year. (If it lasts that long!)

  13. This recipe makes 2 half pint jars jam.

  7. I have never tried blackberry jam before but this recipe looks delicious. Reminds me of being in my grandmas kitchen when she would give me a tea biscuit with her homemade raspberry jam and some tea. Funny how certain foods bring up memories. Thanks for sharing.

  9. Incredible! How do you manage those 2 acres of wild blackberries?! I do make a mistake of getting my hand out quickly (I have a few bushes of wild berries that have thorns). But that is only because I am anxious to use them in another recipe! Great jam!

    • My husband and Father-in-law mow large strips to walk, so that you don’t have wade through the middle of them. Then every 4 or 5 years we you a brush hog to mow them and all of the small tree saplings down so that the area doesn’t turn into forest. Thank you Jacqui!

  10. I so agree with you to reducing the sugar in jam. It definitely doesn’t need so much sugar to be delicious. What a great recipe for a beautiful scone with some clotted cream absolutely yummmyyy 🤤
