Here we go…with a session of making homemade jam. I have a few blackberries remaining in my backyard bramble patch. How do I use the precious berries? I thought of my mother’s great blackberry jam. Plus, my sister-in-law gifted me a case of 1/2-pint canning jars. Now, you know that you’re a kitchen geek when you get excited about receiving canning jars as a gift! The blackberres are not enough for a batch of “real” blackberry jam, so I’m combining them with apples. It’s a small batch; easy to make at home. Plus, I preserved them using a stock pot with an insert in the bottom for my boiling water bath processor rather than a “real” home canner. Now they are shelf stable.

Springtime in Louisiana brings wild blackberries in sunny patches. My backyard blackberry patch “sprung” up in one of my flower beds which I had not been tending. It was an unintended bonus to being a lazy gardner. I got several nice pickings of the blackberries and still have two cups remaining. I thought about making some delicious blackberry jam.

Blackberry & Apple Jam Recipe
I searched through all my recipe books for jams and jellies and couldn’t find a recipe which used only two cups of blackberries. I decided to concoct my own recipe by adding enough apples to make fruit for a batch of jam, scaling back on the quantities of ingredients as much as possible. My recipe makes 5 jars which are 1/2 pint (8 ounces). The resulting jam tastes great!
Here are the ingredients:

Along with the 2 cups of blackberries, I added 2 Granny Smith apples (4 cups diced apples). The other ingredients are the juice of 1 lemon, 2-1/2 cups sugar, 1-1/2 cup water and 1 box (1.75 oz) powdered pectin.
Making the Jam
To make the jam, mash the blackberries and core and dice the apples. I left the peelings on the apples, but if you prefer, peel the apples first.
Cook the apples in 1 cup of water and the lemon juice the stove until the apples are soft and mushy. This takes about 15 minutes. I mashed most of the cooked apples with the back of a wooden spoon.
The blackberries yield one cup when mashed. The soft apples also cooked down, too. I figured that I needed three cups of mashed fruit, so I added enough water to make three cups total of the blackberry and apple mixture.
Jams and jellies are basically a combination of fruit, pectin and lots of sugar. Although most fruit probably has enough pectin naturally so that you don’t need to add more, I’m cautious. I added a box of powdered pectin to my blackbery and apple mix.
There’s a specific way to add pectin when making a jelly or jam.
- Add a small amount of sugar to the powdered pectin and then stir this into the fruit mixture on the stove.
- Cook over high heat. When the fruit and pectin mixture comes to a rolling boil — one which doesn’t stop when you stir the fruit — add the remaining large about of sugar.
- Time and cook exactly one minute — stirring constantly.
- Immediately pour into hot sterilized jars. A funnel made for canning is helpful here.
- Add new rings and seals which you have sterilzed by boiling in a small pot for 5 minutes. I have a handy magnetic gadget for transferring the rings and seals out of the hot water.
Heat Processing the Jam
At this point, the jam can either be stored in the refrigerator — it should keep for several months — or heat processed in a boiling water bath to make it shelf stable.
To process this small batch, I used a tall stock pot with a colander insert. This insert, with holes, allows the boiling water to circulate under, around and on top of the jars. The water should cover the jars by 2 inches.
Bring the water in the stock pot to a rolling boil — one which doesn’t stop boiling when you add the jars. (This can take 15 minutes to 30 minutes, so I get this ready first.) Add the jars of jam, and return to a rolling boil. (This takes a couple of minutes.) After the water is boiling, set the timer for 5 minutes and process.

I have some tongs made for canning, which are handy to use. We’re dealing with boiling water and it is easy to scald yourself, so used kitchen mitt or a durable tongs to transfer the jars in and out of the boiling water.
Remove the jars from the boiling water and set them on a clean towel on a tray to cool down. Check the seals to make sure they are sealed properly. Store any which haven’t sealed in the refrigerator.
We have a small batch of delicious “Blackberry & Apple Jam.”

A Small Batch of Apple & Blackberry Jam
Ingredients:
- 2 cups fresh blackberries
- 2 (1 lb) Granny Smith apples (4 cups, diced)
- 1 cup water plus about 1/2 extra cup
- juice of 1 lemon
- 2-1/2 cups sugar
- 1 (1.75) oz box powdered pectin
Method and Steps:
- Get the canning process ready by sterilizing 5 jars which are 1/2 pint (8 oz) size. Either sterile in a dishwasher or, alternately, fill a large stock pot with colander insert with water. Add the jars and boil for 5 minutes. (Heating the stock pot can take from 15 to 30 minutes.) Also, sterilize new rings and seals in a small pot of boiling water for 5 minutes. Set the jars, rings and seals aside while making the jam.
- Sort the blackberries, remove stems, debris, bugs, etc. Mash with a potato masher. Yield should be 1 cup. Set aside.
- Core the apples, cut off stem and blossom end. If desired, peel the apples. Dice the apples into small pieces.
- Add the diced apples, juice of one lemon and 1 cup of water to a heavy medium-sized pot. Bring to a boil, and then turn down heat to a simmer. Cook until soft, about 15 minutes, stirring occasionally. Mash most of the apples using the back of a wooden spoon.
- Remove from heat, cool until apples can be handled. Measure blackberries and apples. Add enough water (about 1/2 cup) so that the mixutre equals 3 cups. Pour this mixture back into the heavy pot.
- Measure out 2-1/2 cups sugar in a small bowl. Set aside.
- Combine 1/2 cup of the sugar from this amount with the powdered pectin in another small bowl. Add to the mashed fruit and water jam mixture.
- Return the jam to the stove. Over high heat, bring the jam to a rolling boil. Stir constantly.
- When the fruit is boiling rapidly, quickly add the reserved (2 cups) sugar. Return to a rolling boil. Time and cook for exactly one minute.
- Quickly remove from heat and fill the sterilized jars with the jam. Add the sterilized seals and rings.
- Either store in the refrigerator or process in a canner in a boiling water bath for 5 minutes so they will be shelf stable. Check the lids to make sure they have properly sealed.*
*NOTE: To process this small batch, use either a home canner or a tall stock pot with a colander insert. This insert, with holes, allows the boiling water to circulate under, around and on top of the jars. The water should cover the jars by 2 inches.
Bring the water in the stock pot to a rolling boil — one which doesn’t stop boiling when you add the jars. (This can take 15 minutes to 30 minutes, so I get this ready first.) Add the jars of jam, and return to a rolling boil. (This takes a couple of minutes.) After the water is boiling, set the timer for 5 minutes and process. Using tongs made for canning, remove the jars from the water bath and let cool on a tray lined with a cloth towel. When cool, check to make sure jars are sealed properly. If sealed, the jars are shelf-stable. If not sealed, store in refrigerator.











Small batches of jams make so much sense! Unless you are planning on gifting a lot of jams, and i sometimes do, the work involved in production can seem intimidating.
Hello, yes, I agree, it is easy to make a small batch in an evening — which makes it a do-able project.
I love that you’re finding ways to use up those gorgeous berries that nature has given you! And nice that you’ll be able to enjoy the jam later in the year when you need a taste of spring sunshine.
Thanks — the jam didn’t last long! this has me in the in the spirit for some other fruit jams later this summer!
