Blackberry Jam - Fresh Berry Recipe and Hot Water Bath Canning tutorial (2024)

Ever since I was a little girl, our family has enjoyed homemade Blackberry Jam. The Ozark mountain roadside near my late Grandma Gracie's home had dozens of blackberry bushes that produced plenty of fruit.

Back then, before there was a McDonalds and a Taco Bell around every corner, people would actually pack their own "to-go" food for road trips. Sometimes, Grandma Gracie would make her one-of-a-kind sandwiches and treats for us to enjoy on our long drive home after a visit to her house.

To give you some perspective, Grandma Gracie was born in 1888. She married young to a farmer who became the local minister and postmaster, gave birth to twelve children at home, raised all her children, and lived her entire life (over 90 years) in a very rural area of Texas County, Missouri.

If we wanted jam or cobbler, all we had to do was pick the blackberries. Grandma Gracie would turn those berries into jams and cobblers for us, and it was the best stuff on earth.

Today, I live far away from the old Ozark Mountain family farm, and I miss the taste of her Blackberry Jam. HEB had a sale on fresh blackberries. That was motivation enough for me to make some jam. I bought two cases (12 tubs per case) of their 6 oz. tubs. For your reference, that purchase of 24 tubs made enough jam to fill 27 half-pint (8 oz.) jelly jars.

Making Blackberry Jam conjured up wonderful memories of my dear Grandma Gracie. Her irresistible Blackberry Jam and real dairy butter, spread between two slices of her famous homemade bread....those were the best sandwiches ever. You just can't buy "to-go" food like that at McDonalds.

There are plenty of great Blackberry Jam recipes available. Because I know and trust the Ball brand, I chose to use a recipe that uses Ball Fruit Pectin.

Here is the recipe I use from the Ball Real Fruit Classic Pectin Label. The red arrows and dots are the steps I followed for Blackberry Jam.

I'm including these photos from my own Ball Blue Book as a reference for quality information on proper procedures for hot water bath canning or "boiling water" canning. The 1995 Ball Blue Book Volume I is available on amazon.com, or you can buy the latest edition here on the Ball website .

When buying blackberries, the fresher the better. Prepare your jam as soon as you can when you get them home. Start by sorting through all the fruit, discarding unusable berries. Rinse thoroughly in a very clean sink filled with fresh clean water. I placed a dish towel in the bottom of the sink to keep the tender berries out of the sink strainer.

After rinsing, take a handful of berries and place them in a colander.

Spray the fruit in the colander with a solution of 50% water and 50% white vinegar.

As a side note: I use vinegar water to clean my sink, countertops, and other kitchen surfaces. It is a great disinfectant and much safer than chemical sprays.

Vinegar Water Cleaning Spray

After spraying the fruit with the vinegar water. rinse thoroughly with running water to remove the vinegar. Drain excess water.

Place your drained berries in a medium size bowl.

Mash berries up well until you have a lovely, juicy pulp. The directions suggest using a potato masher, but I prefer my pastry cutter to do this part. It's rounded shape fits the bowl much better than a flat potato masher.

Your berries should resemble the berries shown in the photo below when they're mashed.

The color is just beautiful.

In my case, one 6 oz. tub of fresh berries made just over 1/2 cup of pure berry pulp.

When you're done mashing the berries, place your mashed blackberry pulp into a large pot. Gradually stir in pectin and mix well. Then, heat until you bring mixture to a full rolling boil that cannot be stirred down, over high heat, stirring constantly. Add entire measure of sugar, stirring to dissolve. Use good quality sugar. Cheap sugar is fine for Koolaid, but don't ever use cheap sugar when canning or baking. Good sugar dissolves much better. Return mixture to full rolling boil. Boil hard for one minute, stirring constantly. Remove from heat.
