I am one lucky girl. My mother made everything from scratch when I was a kid. As grateful as I was to always have food… great food, I didn’t fully realize how good I had it until I went to college and ran out of my mom’s homemade jam. I decided to grab a jar off the shelf at the store, used it once, and never touched it again. It just didn’t compare to the scrumptious taste of mom’s freezer jam. Once you try blackberry freezer jam, you’ll never go back to cooked.

What makes freezer jam so good?

So why is freezer jam so amazing? 

First, freezer jam has amazing flavor. Freezer jam is not cooked, so the integrity of the flavor of the berry stays intact and true to how a fresh berry tastes. When berries are cooked, their taste changes- and it’s not always for the better. I notice it most with strawberries.

Second, you don’t have to know a thing about canning methods when you’re making freezer jam. This is not a recipe where you will be storing in on your pantry shelf for months to come.

Third, no special equipment is needed! I hate having my cupboards filled with things I use just once a year. For this recipe, all you need are containers- plastic or jars, a pot, a potato masher, and a freezer. I’m pretty sure you’ve got all of these but if you don’t then they are very affordable to buy. 

Fourth, freezer jam is more spreadable. Sometimes cooked jam or jelly is as thick as jello and so awkward to spread on bread. Freezer jam is thinner/more runny than cooked jam, and it’s only heated on the stove briefly to dissolve the sugar.

Can you store freezer jam in the refrigerator?

Yes! Freezer jam will last three weeks when stored in the refrigerator, and it’s good for 6 months in the freezer.

I’ve tried many flavors of jam but my current favorite is this Blackberry Freezer Jam. Of course, you need to start with prime berries that are sweet and not tart. I like to spread this jam on English muffins, toast and peanut butter sandwiches. You’ll want to eat it on everything! Enjoy!

Ingredients

Instructions 

  • In a large pot (off the stove), mix the blackberries and lemon juice together, and sift in the pectin a little at a time while stirring.
  • Once all the pectin is mixed in, set a timer for 30 minutes and give the fruit a stir every 7 to 10 minutes.
  • After the 30 minutes, stir in the corn syrup and then place the pot on the stove over medium heat. Stir in the sugar a little at a time and cook for about 5 minutes until the sugar is dissolved (it should be good to go when the jam reaches 100 degrees F or you can just rub it between your fingers to make sure you don't feel any grains). If it is cooked longer it will be quite runny.
  • Pour the jam into clean plastic containers or glass jars and place in the fridge and/or freezer.

Notes

  • Jam lasts about 3 weeks in the fridge and up to 6 months in the freezer.

    What can I substitute for the corn syrup? I am allergic to corn.

    1. Lori Lange says:

      I’m not sure– try Googling substitutions, perhaps?

    Made this recipe yesterday and it turned out so well I’m planning another batch! I did remove the seeds as personal preference.

    On the second batch – can I process these in a water bath at the end so they will last up to a year on the shelf?

    1. Lori Lange says:

      I’m not so familiar with traditional canning techniques, so I’m not sure. I would think so, though.

    2. Patti Paul says:

      I’d love to try this recipe. Could you share how you removed the seeds? Thank you.

  3. Valerie L Eisenacher says:

    Can you strain the seeds out?

    1. Lori Lange says:

      yes

  4. Coleen hawkins says:

    I just made your BlackBerry jam recipe. On the back of the sure jel pectin box it said to leave on counter for 24 hours to set….on your recipe you said to put in freezer or fridge after putting jam in the jars….
    Would leaving them on counter for 24 hours make a difference for thickening….I would like it a little more thick.

    1. Lori Lange says:

      I’m not sure!

  5. Patricia Baltic says:

    Can I use honey as a replacement to the sweeteners you have listed? Thank you.

    1. Lori Lange says:

      I haven’t tried honey, so I’m not sure.

  6. Nikhol says:

    I followed the directions to a “t” when I filled the jars I put lids on and put in fridge. They have firmed up some but will they firm up more overnight?

    1. Lori Lange says:

      They should- how did they turn out?

  7. Gail Eliza says:

    Loved this easy recipe..turned out perfect…
    Could you use blueberries in this same recipe ?

    1. Lori Lange says:

      I haven’t tried that, but I would assume so!

    Yes, please! I love blackberries and I love freezer jam. I even have some frozen berries from the summer that I can use. Can’t wait to make this and enjoy it on my favorites biscuits.
