Blueberry Jam Recipe (With Pectin and Canning Instructions) (2024)

This blueberry jam recipe is made with fresh or frozen blueberries. There is also a low-sugar recipe option for this small-batch blueberry jam that is equally as delicious.

We are huge fans of fresh blueberries and are fortunate to live in a region that has may pick your own blueberry farms. This year we picked over 17 pounds of blueberries and I am working my way through turning them into the best blueberry syrup, lemon blueberry bread and a batch of blueberry salsa after I pull this recipe of blueberry jam out of the water bath canner.

Ingredients needed to make homemade blueberry jam recipe

• Blueberries, fresh or frozen
• Lemon juice, I prefer fresh
• Ball Classic Pectin
• Sugar

How can the sugar in blueberry jam be lowered?

If you have blueberries that are super sweet that you don't want to add more sugar than needed or if you like a lower sugar jam there is an easy recipe adjustment.

• Add ⅔ cup of water or unsweetened fruit juice, just as apple or pear, to the blueberries and lemon juice.
• Substitute 3 Tablespoons of Ball Low or No-Sugar Needed Pectin in for the Classic pectin.
• Reduce the sugar to 1 cup.
• The jam will be looser in consistency and set than the classic recipe but will still be delicious!

What materials do you need to make blueberry jam making?

• Water bath canner and rack (a large stock pot will work as long as it is big enough to hold enough water to cover your jars by 2 inches when submerged)

• Clean towels to rest the hot jars.
• Paper towels dampened to wipe the jar rims.

5 Days To Canning Confidence

How to make blueberry jam:

1. Rinse and drain the blueberries (fresh or frozen) and crush them using the potato masher method or my rolling pin and zip top bag method.
2. Measure out 2 ⅔ cup of crushed berries into a 6 quart stainless-steel or enamel Dutch oven.
3. Stir in the lemon juice and the pectin.
4. Over high heat, while stirring, bring the mixture to a full rolling boil that can not be calmed down when stirred.
5. Add the sugar and stir to dissolve the sugar. Return to a full rolling boil. Boil hard 1 minute, stirring constantly.
6. Remove from heat and skin the foam, if necessary.
7. Ladle the jam in to a hot jar, leaving ¼ inch head space. Wipe the rim of the jar with a damp paper towel, removing any drips of jam.
8. Center the lid on the jar. Apply the band and adjust to fingertip-tight. Using the jar lifter, place the jar in the boiling water canner.
9. Repeat until the jars are filled. Be sure to complete filling a jar from ladle to lifting before starting the next jar.
10. Process the jar 10 minutes, adjusting time for altitude.
11. Remove the jars from the water bath canner and place on clean towels to cool completely.
12. After 24 hours, test lids for seal, remove rings and store in a cool dry place.
13. Be sure to store any jars with lids that did not seal in the refrigerator.
