This blueberry jam recipe 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 batch canner.
Ingredients needed to make blueberry jam?
- 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!

Frequently Asked Questions With The Answers
This recipe calls for a pound, dry pint or 3 cups of fresh blueberries. Frozen blueberries can be substituted and the recipe will yield 4 (½ pint) jars.
Homemade blueberry jam properly made and processed by canning in a hot water bath, can be expect to have a shelf life of 18 months to about two years when properly stored in a cool, dry place. Once opened, keep homemade jam in the refrigerator for up to three months.
It is often written that it is good to crush blueberries, 1 layer at a time, on a rimmed cookie sheet with a potato masher.
But I have found that the best, fastest and least messy way to crush blueberries is place them in a gallon zip top bag, remove the air, close the bag and crush the berries with a rolling pin!
Still make sure they are in a single layer but this way the berries don't squirt you and they can be easily poured into the post for the next step in jam making. 
The beauty of this recipe is that you can substitute frozen blueberries for fresh ones. No need to thaw ahead and the measurement is still the same! 3 cups of berries. I show you how to freeze blueberries and jam is a great use for these frozen berries if need to make more jam in the colder months. Use either fresh for frozen blueberries to make blueberry syrup and be sure to follow the canning instructions!
