It’s blackberry season, and you’re going to LOVE this no cook, low sugar, homemade jam! It’s perfectly sweet, only takes about 10 minutes to make, and lasts for an entire year! We grow a TON of raspberries, blackberries and strawberries in our backyard, and this is our favorite way to preserve them to enjoy through the in the winter!
Just like my strawberry freezer jam, this is a blackberry freezer jam WITHOUT pectin. It’s a great recipe that your can use fresh or FROZEN blackberries to make!
Blackberry Freezer Jam
When I was growing up, my mother made just about everything from scratch…. EXCEPT for Jam. The first time I tried freezer jam, I was in shock. I never thought jam could be so good!
Nowadays, I’m pretty much a Jam SNOB. If it’s cooked, over-processed, over-sugared, and not mostly fruit… I don’t care for it!
Freezer jam is exceptional because it’s FRESH! Freezer jam is not cooked, so it tastes the most like fresh berries, and it’s the easiest way to make jam! It’s also WAY LESS SUGAR! Traditional jams are LOADED with sugar… In fact, they’re MOSTLY sugar! However, freezer jam is mostly fruit, with a little bit of sweetener if needed!
We enjoy this homemade freezer jam on ice cream, biscuits, fluffy sourdough pancakes, sourdough waffles, English muffins, yogurt and sourdough bread! This is my favorite jam, and in my humble opinion, there’s no better way to preserve ripe blackberries;)
How To Make Blackberry Jam
This easy blackberry freezer jam recipe is so ridiculously simple to male, and only has 4 ingredients! Simply combine fresh (or frozen) blackberries, lemon juice, a tiny bit of sugar, and thickener… Then blend well! If you like chunkier jam, crush blackberries with the potato masher instead;)
Blend till desired texture and taste test! Once you’re happy with your freezer jam consistency, it’s done, easy peasy! Fill your clean jar leaving an inch of space at the top of the jar for expansion when it freezes. Either enjoy it now or freezer for later! It lasts for a year in the freezer if there’s any left!
Simple Ingredients
- 4 cups fresh fruit – Blackberries in this case!
- 1/2 cup sugar (traditional jam recipes call for multiple cups of sugar, this is less sugar and more fruit!)
- 1/4 cup fresh lemon juice, or lemon juice concentrate (Lemon really compliments the blackberry flavor, and it preserves color.)
- 1/3 cup Ultra Gel or EZ Gel – Thickener
- *optional – 1/4 cup sugar (or sugar substitute)
Tools
- Blender, Food Processor or Potato Masher – To blend blackberries & other ingredients till smooth.
- Measuring Cups – Measure all ingredients.
- Large Bowl
- Ultra Gel Thickener – or EZ Gel Thickener – Thickens freezer jam without cooking!
- Freezer Jars – Store well in the freezer without cracking or leaving harmful chemicals in food! I like to use these small freezer safe glass jars because it’s the perfect amount for one family breakfast topping.
- *Optional – Freezer Jam Lids – Reusable freezer lids!
- That’s it… no special equipment!
Why You’ll Love This Easy Recipe
- No Cook – This recipe requires no cooking at all… This blackberry freezer jam is not processed, giving it a fresher, more natural flavor!
- Easy! – No need of canning knowledge, no water bath, no fuss!
- Fast! – This blackberry freezer jam only takes a few minutes to put together. Then enjoy or freeze!
- Lower Sugar – Even the best jam recipes call for too much sugar! This blackberry freezer jam has the lowest sugar of them all! And if that’s still too much, you can omit it completely and it will still thicken and be delicious!
- Naturally Fresh! Because this is fresh (not cooked) freezer jam… It’s mostly fruit!
Sugar Free Blackberry Freezer Jam- Yes You Can!
If you want to make sugar free blackberry freezer jam, I recommend using erythritol.
Erythritol is a sugar alcohol made with yeast that actually ferments the sugar in corn and wheat starch. It has way less calories than regular sugar, and other sugar alcohols too. For example:
- Sugar has 4 calories per gram.
- Xylitol is 2.4 calories per gram.
- Erythritol has only 0.24 calories per gram.
Erythritol only has 6% of the calories that regular sugar has, and still gives 70% of the sweetness of sugar!
Ultra Gel or EZ Gel Freezer Jam Thickener
Ultra Gel, and EZ Gel thickeners are both modified food starch made with potato starch or cornstarch. They use an enzyme to change the starch in corn or potatoes so that you don’t have to cook it to thicken!
They both thicken any liquid whether it’s hot or cold. They are GREAT thickeners to keep on hand, and it’s wonderful for raw jams like this.

The Ultra Gel seems to be out of stock everywhere. What other brand name would be a good substitute?
