How to Make Blackberry Jam
-
Slice blackberries. If your blackberries are on the larger side, slice them in halves or quarters to ensure even cooking. While prepping, pop two saucers into the freezer to check your jam’s consistency later.
-
Combine ingredients. In a medium saucepan, stir together the sliced blackberries, granulated sugar, and fresh lemon juice until fully mixed. This creates the foundation of your fragrant jam.
-
Dissolve sugar. Over medium-low heat, gently bring the mixture to a simmer. Stir continuously for about 5 to 8 minutes until the sugar has completely dissolved, and you can see the vibrant blackberry juices beginning to flow.
-
Bubble time! Stirring frequently, increase the heat to medium and allow the mixture to bubble for 10 to 15 minutes. You’ll know it’s ready when it thickens and looks syrupy, turning a deeper, richer hue.
-
Test the setting point. Remove your pan from heat and drop a small dollop onto one of the cold saucers. Run your finger through it; if it holds its shape and wrinkles a bit, you’ve reached the perfect jam consistency! If it’s still too runny, return it to the heat, boiling for another five minutes before testing again.
-
Jar the jam. Ladle the hot jam into sterilised jars, leaving about 2 cm of space from the top to allow for expansion. Seal immediately with a screw-top lid for the best preservation.
Optional: Serve your blackberry jam with warm biscuits for a delightful treat!

Make Ahead Options
Homemade Blackberry Jam is a great option for meal prep lovers! You can slice the fresh blackberries and mix them with sugar and lemon juice up to 24 hours in advance, storing the mixture in the refrigerator to maintain quality. This step not only saves time but allows the flavors to meld beautifully! When you’re ready to make the jam, simply transfer the chilled mixture to the saucepan and follow the cooking instructions as usual. Just be sure to check the consistency is right during the cooking process, as it may require slight adjustments if the mixture sits overnight. With these tips, you’ll be savoring that delicious homemade blackberry jam with minimal effort!

Blackberry Jam Recipe FAQs
How do I choose ripe blackberries for my jam?
Absolutely! Look for blackberries that are plump, firm, and free from dark spots. The ideal berries should have a deep black-purple hue and feel slightly soft to the touch but still hold their shape. If they smell sweet and fruity, they are likely perfectly ripe for making delicious jam!
How should I store my blackberry jam after it’s made?
Great question! Once your blackberry jam is sealed in jars, you can store them at room temperature in a cool, dark place for up to one year. After you open a jar, transfer it to the fridge, where it will remain fresh for about 3 weeks. Just make sure to keep it tightly sealed to maintain its yummy flavor!
Can I freeze blackberry jam for longer storage?
Absolutely! You can freeze your blackberry jam for up to 6 months. To do this, make sure your jam is in airtight containers, leaving some space at the top for expansion. A tip I often use is to write the date on the jar so you remember when it was made. When you’re ready to enjoy it, just thaw it in the refrigerator overnight.
What should I do if my blackberry jam doesn’t thicken properly?
Very! If your jam isn’t setting, don’t worry. You can always return it to the stovetop. Simply cook it over medium heat for an additional 5 minutes, then test the setting point again using the cold saucer method: place a dollop on a saucer and check for a gel-like consistency. If needed, repeat this process until it reaches the right thickness!
Are there any dietary concerns I should consider with blackberry jam?
Definitely! If you or anyone in your family has allergies, be mindful of the sugar content and the possibility of cross-contamination in jars. For those on low-sugar diets, consider reducing the sugar amount or replacing it with natural sweeteners like honey, but keep in mind that this may affect the jam’s setting. Always consult your healthcare provider if you have specific dietary restrictions!
What should I do if my blackberries are slightly overripe?
No worries at all! Even slightly overripe blackberries can still work well for jam. Just ensure there are no moldy spots, and cut away any blemishes. They might actually yield more juice, making your jam even more delicious. You might want to slightly adjust the sugar as overripe fruit can be sweeter!
