Ball Canning Blackberry Jam Recipes

BLACKBERRY JAM

Steps:

• In a large saucepan or Dutch oven, combine blackberries and sugar. Let stand for 15 minutes.
• Use a potato masher to mash the berries in the pot, releasing the juices.
• Bring the mixture to a boil over medium heat. Once the mixture boils, add the lemon juice; cook, stirring frequently, until the mixture thickens and coats the back of a spoon, about 15-20 minutes.
• For a thicker jam, whisk together pectin and 1 tablespoon of sugar. Sprinkle the pectin mixture over the jam and stir to combine. Cook for exactly 1 more minute, then remove from the heat.
• Divide the jam between 2 sterilized 8-ounce glass jars, leaving ¼-inch of headspace at the top of each jar. Wipe the rims clean with a damp cloth, then secure the lids and bands.
• Process in a water bath for 10 minutes. Carefully remove the jars to a towel on the counter. Let stand, undisturbed, for 12 hours at room temperature. Check the seals after 12 hours by pressing the center of the lids. If the lid gives or the center button remains popped up, store in the refrigerator for up to 1 month. Properly sealed jars will keep in a cool, dark place for up to 8 months. Refrigerate after opening.

BLACKBERRY JAM RECIPE

Steps:

• Prepare calcium water from Pomona pectin. Put 1/2 tsp calcium powder (the small package) and 1/2 cup water in a small jar with a lid. Shake well before using.
• Fill a canning pot with water, set the lid in place, and heat on high heat until just boiling while you're cooking the jam.
• Wash the berries and mash using a potato masher. Leave some larger chunks if you like your jam chunky or really pulverize the fruit for a less chunky blackberry jam.
• Measure mashed berries into a large pot along with 4 teaspoons of the prepared calcium water.
• In a separate bowl, combine the sugar with 4 teaspoons pectin powder (the large envelope) until thoroughly combined.
• Bring berries to a full boil. Add sugar mixture, stirring vigorously for a couple of minutes to dissolve the pectin. Once returned to a full boil, remove from heat.
• Ladle hot berry jam into half-pint jars to within a quarter inch of the rim. A canning funnel makes this easy.
• Wipe jar rims to remove any jam that may have spilled. A clean rim is essential to a good seal.
• Set jar lids in place. Screw bands on finger tight.
• Use a jar lifter to gently submerge jars into hot water in canning pot. Water should cover the top of the jars by an inch. The water will cool somewhat in reaction to the addition of the jars. Return the water to a low boil and then set the timer.
• Process in a boiling water bath for 10 minutes. Add a minute to the boiling time for every 1,000' above sea level.
• Check seals. Lids should be solid and pulled down tight. (if they flex and pop, the jar didn't seal; put unsealed jars in the refrigerator and use those first).
• Remove rings and wash outsides of jars. Store in a cool, dry place.

BLACKBERRY JAM

Steps:

• (If you are planning to can the jam, prepare waterbath and sterilize jars).
• Clean berries just before using. Add the blackberries and lemon juice to an extra-large saucepan. Mash with a potato masher and simmer for a few minutes, to break down the fruit.
• (Optional, but recommended:) Use a food mill, or press mixture through a fine mesh strainer, into a bowl, to remove seeds.
• Measure out 4 cups of berry juice and add to an extra-large heavy bottomed stock pot. Add 2-3 spoonfuls of the leftover seeds for blackberry "jam". (Jelly uses the juice only).
• Add sugar and stir to combine. Turn burner to medium low, stirring occasionally, cooking for several minutes until sugar has dissolved.
• Increase the heat to medium high, and cook, stirring constantly, until the mixture comes to a full boil (a rolling boil that can't be stirred down).
• Add the pouch of pectin, stirring continuously, and allow to return to a full boil. Set a timer for 1 minute, stirring continuously, and remove from the heat after 1 minute.
• Pour jam into prepared jars and seal with lids.
• For Freezer Blackberry Jam: Allow the jam to cool at room temperature for 24 hours, then store in the fridge for up to 1 month, or the freezer for up to 1 year.
• To Can: Process in a boiling water bath for 10 minutes (or longer if at high altitude*). Allow to rest on your counter for 24 hours, to ensure the jars settle and seal properly. Check seals, and store jam in a cool, dry place for up to one year.

BLACKBERRY JAM

Steps:

• Place the berries in a large stainless steel or enamel saucepan. Bring to a full boil over high heat, mashing the berries with a potato masher as they cook. Add the lemon juice and boil hard for 1 minute, stirring and mashing constantly.
• Add the sugar and return the mixture to a boil. Cook, stirring constantly, until it begins to look syrupy and thickens slightly, about 5 minutes. Remove from the heat and test for doneness: a candy thermometer should register 220 degrees F and the mixture should coat the back of a spoon. Run a finger--or a clean object about the width of a finger--through the coat of jam. If the jam does not run and fill the gap, it is done. Otherwise, return the pan to the heat for another 1 to 2 minutes and test again. Be careful not to let the mixture get too thick--it will thicken as it cools.
• When the jam is done, transfer it to a heatproof jar and cool to room temperature, about 2 hours. Cover with a tight-fitting lid and refrigerate. The jam will keep for up to 2 weeks.

Steps:

• Mash blackberries in a saucepan with a potato masher. Stir in sugar until juices form; place about 1 tablespoon blackberry juice in a small bowl and stir in cornstarch. Pour cornstarch mixture into saucepan.
• Bring berries to a boil, stirring often, until jam is thickened, about 15 minutes. Stir in cinnamon and allspice. Remove from heat and allow to cool. Transfer jam to a bowl, cover, and refrigerate until chilled. Stir in lemon juice.

SURE.JELL BLACKBERRY JAM

Steps:

• Bring boiling-water canner, half full with water, to simmer. Wash jars and screw bands in hot soapy water; rinse with warm water. Pour boiling water over flat lids in saucepan off the heat. Let stand in hot water until ready to use. Drain jars well before filling.
• Crush berries thoroughly, one layer at a time. (Press half the pulp through fine mesh strainer to remove some of the seeds, if desired.) Measure exactly 5 cups prepared fruit into 6- or 8-qt. saucepot.
• Stir pectin into prepared fruit in saucepot. Add butter to reduce foaming. Bring mixture to full rolling boil (a boil that doesn't stop bubbling when stirred) on high heat, stirring constantly. Add sugar; stir. Return to full rolling boil and boil exactly 1 min., stirring constantly. Remove from heat. Skim off any foam with metal spoon.
• Ladle quickly into prepared jars, filling to within 1/4 inch of tops. Wipe jar rims and threads. Cover with two-piece lids. Screw bands tightly. Place jars on elevated rack in canner. Lower rack into canner. (Water must cover jars by 1 to 2 inches. Add boiling water, if necessary.) Cover; bring water to gentle boil. Process 10 min. Remove jars and place upright on towel to cool completely. After jars cool, check seals by pressing middle of lids with finger. (If lids spring back, lids are not sealed and refrigeration is necessary.)
