It takes only around 30 minutes to prepare, and you can even make it without pectin.

Tips on Making Blackberry Jam

Traditional blackberry jam recipes call for equal amounts of fruit and sugar. It helps achieve a bigger yield and preserve the jam longer. But in this low-sugar recipe, we let the fruity flavor really shine through. Meanwhile, we suggest keeping these tips in mind when making this easy berry jam recipe:

If you’re using wild blackberries, make sure to soak them in salted cold water for at least 20 minutes. This helps remove any impurities that might have settled into the crevices of the berries. Use 1 tablespoon of salt for every 4 cups of water. Drain the fruits well before using.

If you want a more chunky jam, soak the fruits in sugar overnight. Letting the fruit sit in granulated sugar helps draw out most of the juice from the fruit. As a result, the fibers of the berries are more intact and won’t easily break down when cooked. To macerate, use the amount of sugar called for in the recipe. No need to add more when cooking.

Use fresh and slightly under-ripe berries and you will not need to add pectin anymore to thicken your jam because they’re already naturally high in pectin. Blackberries lose pectin as they ripen, but they get sweeter. So if you happen to only have overripe berries or frozen berries, then we suggest making this blackberry jam recipe with pectin.

Lemon juice enhances the fruitiness of this jam. If you want to explore other flavors, add a dash of cinnamon or a few drops of vanilla or almond extract to your blackberry preserves. You can also add a handful of toasted almond slivers for some crunch!

Frequently Asked Questions

How do you get seeds out of blackberry jam?

The sour and bitter flavors in blackberries are concentrated in the seeds. To remove the blackberry seeds, mash the berries first, then strain the mixture. Most of the pulp will also be removed leaving you a smooth juice that can be cooked and turned into blackberry jelly.

Will my jam thicken as it cools?

Yes, pectin sets as it cools. It takes about 1 to 2 days for the jam to be fully set. However, there is a way to test the consistency while cooking it. Place a small ceramic saucer in the freezer for 5 minutes or until chilled. Then, take a pea-sized portion of the jam and put it on the chilled plate to quickly cool it down. If it doesn’t move when you tilt the plate, it means that the batch will thicken.

How to store blackberry jam through water bath canning method?

The water bath canning method is an effective way of extending the shelf life of fruit jams for up to 18 months. Make sure to sterilize the jars and have them ready to be filled by the time the jam is done. First, have a water bath canner or a big pot of boiling water ready. Sterilize the canning jars, lids, and metal screw bands in another pot of boiling water for at least 15 minutes. Lay the jars and lids in a kitchen towel-lined baking sheet. Fill them with the hot jam, screw the lid, then place them in a canner rack or directly to the pot. They should be submerged in at least 2 inches of water at a rolling boil for at least 5 minutes. Allow them to cool for at least 24 hours before storing them in the pantry.
