Author: Learn how to make homemade blackberry jelly from fresh or frozen blackberries. This old-fashioned blackberry jelly recipe is made without pectin or Sure Jell! You can use this blackberry jelly recipe for canning or for enjoying fresh!
Fresh blackberry jelly is a seasonal delight around here since we have 40+ blackberry bushes that explode with fruit for about 4 weeks in the spring. I usually stay inside washing and canning juice and jelly while my husband is out harvesting all the blackberries.
I used to feel bad about that and thought that I should be helping him. But he gets to be out in the fresh air for about an hour while I’m standing at the hot stove for 4-6 hours at a time! Ha!
However don’t be discouraged, I’m usually canning several gallons of jelly every day for weeks, so your blackberry jelly canning experience it likely going to be much easier!
Even still, I wouldn’t trade it for the world, because this recipe is such a treat for us throughout the entire year! Our favorite way to eat this blackberry jelly is on warm homemade biscuits or freshly baked bread!
Homemade Blackberry Jelly
One of the reasons we make blackberry jelly instead of blackberry jam is for my dad who suffers from diverticulitis, which is often triggered by seeds and nuts.
It’s been a few years since we ditched blackberry jam and we haven’t looked back! One of my favorite things about this jelly is that it’s a great substitute for Concord jelly if you run out early, or if you don’t grow your own grapes.
Ingredients
While the ingredients for this blackberry jelly are straightforward, let’s go over them quickly as there are some possible substitutions.
- Blackberries – You can use fresh or frozen blackberries for this recipe, they will process the same way. If using frozen, thaw them in a large bowl and collect all the juice as they thaw.
- Sugar – We use organic, unprocessed cane sugar, however any white sugar will work the same way. If using honey or maple syrup, note that your jelly will not set the same way during the cooking process. You will need to heat the mixture for much longer to reduce the water content of the jelly before moving on. If using honey or maple syrup, you will also reduce the measurement by 1/4.
- Lemon Juice – This is crucial for raising the acid level and for helping the jelly to gel properly. There is no substitute for this.
Making Juice for Blackberry Jelly
Before you can make blackberry jelly you need to first make blackberry juice. This is really simple to do and only takes a few minutes.
- Wash the berries and remove leaves and bugs as best you can (I don’t worry if there are a few bugs in the berries).
- Put the berries in a saucepan and add a cup of water in the bottom. Crush the berries thoroughly.
- Cover the berries with a lid and place over medium heat.
- Check the berries after about 15 minutes. Heat until the berries are soft, then mash them with whatever you have on hand.
- Strain through a cheesecloth or fine mesh.
Once you have your juice you can continue on with the recipe below.
NOTE: I give the mash to my chickens, but you can use them for fruit leather similar to this strawberry zucchini fruit leather. If you are going to use the strained berry mash for other food products, make sure you thoroughly clean all leaves, twigs, and bugs from the berries before boiling them.
Canning Blackberry Jelly
While you can stop before the canning process if you just want to use your blackberry jelly right away, I’m going to show you how to can it for later. The process of water-bath canning doesn’t require any special equipment and is a great way to add homemade shelf-stable jelly to your pantry!
- Combine juices and sugar in a large saucepot. Bring to a boil over high heat and stir to prevent sticking.
- Bring to gelling point (see notes below). Skim foam if needed.
- Ladle into hot jars leaving ¼ inch headspace. Remove bubbles.
- Clean the rim with a warm wet towel and add two-piece canning lids.
- Process pints and quarts for 10 minutes according to general water bath canning directions.
What temperature is the gelling point?
Gelling point at sea level: Take the temperature of the jelly with a candy or jelly thermometer. The gelling point at sea level is 220°, 8° above boiling.
Above sea level: For each 1000 feet of altitude above sea level, subtract 2 degrees F. For example: at 1,000 feet of altitude, the jelly is done at 218°F; at 2,000 feet, 216°F, etc
Common Questions
That’s ok! For every cup of juice, just use 1 1/2 cups of sugar and 1/2 tablespoon of lemon juice. Don’t process more than 4 cups worth of juice at a time, as the gelling process won’t work right with more juice at a time.
While you can process more berries for juice at a time, it’s not advisable to turn more than 4 cups into jelly at a time. So you can batch process the juice, but then only make one batch of jelly at a time. This is due to the gelling process and how much water is removed during the cooking phase.
Yes! You can reduce the sugar down to 1/2 a cup of sugar per 1 cup of juice, but don’t go lower than that. Also note, that at 1/2 a cup of sugar per cup of juice, the gel set will be very loose, not like a thick jelly. You can use any amount between 1/2 a cup and 2 cups of sugar per cup of juice.

Thank you, Norma! I always forget how much information I take for granted when writing posts. I will add this asap!
Can you use frozen berries from last years picking to make this jelly?
Absolutely!
Looking for a recipe to use with the blackberries I’ve picked, and I’m wondering about the issue of pectin. If you don’t add pectin, do these berries have natural pectin like my black currents do you?
Hi DL! This jelly does set up perfectly and has the same texture as grape jelly. Enjoy!
Thank you for this wonderful recipe!! I wanted to make blackberry jelly for my father and when I was reading the ingredients in the grocery store on the box of pectin it said sodium benzoate and I said no thank you!! The recipe was fabulous.
Awww, Katherine that makes me so happy to hear! I hope you enjoy it for many years to come! <3
About how many blackberries do you start out with?
Hi Carol, I believe it was about a gallon – I can’t remember! We pick everyday and I juice and can daily, so I forget :-\
Can you make the juice a day ahead?
Absolutely!
I made my jelly! How long does it take to fully set up?
Yay Carol!! I usually let it set up overnight :-)
