Canned Blueberry Jam Recipes

EASY BLUEBERRY JAM RECIPE FOR CANNING

Steps:

• Fill a canning pot with water, set the lid in place, and heat on high heat until boiling. It can take awhile for the water to come to a boil, so get it started before you begin making the jam.
• Gather the jars you'll use, making sure each is clean and free of nicks in the rim, which could impede sealing.
• Bring a small pot of water to a simmer and turn off the heat. Drop the rings and lids into the water and leave them there until you're ready to screw them onto the filled jars.
• Combine ½ teaspoon calcium powder (from the small packet in the box of Pomona's pectin) with ½ cup water in a small jar.
• Screw on a lit and shake until well-combined. You'll have more than you need for this recipe.
• Store the excess in the refrigerator for use in making additional jam or jelly recipes.
• Measure the crushed berries, lemon juice, and calcium water into a large saucepan; bring to a boil.
• Meanwhile, combine the sweetener with the pectin until it's thoroughly combined.
• When the berry mixture comes to a boil, stir in the pectin and sweetener, stirring vigorously for 1 to 2 minutes to dissolve the pectin while bringing the jam back to a boil. Remove from heat when the jam boils.
• Ladle hot jam into quarter-pint, half-pint, or pint sized jars, leaving 1/4" head space. 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 the 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 simmer and then set the timer.
• Process for 10 minutes 0-1,000 feet altitude; add an additional minute for every additional 1,000 feet in elevation.
• Remove jars from water using the jar lifter and transfer to a solid, towel-covered surface. Allow to cool for 24 hours.
• 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.

CERTO® BLUEBERRY 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 well before filling.
• Stem and crush blueberries thoroughly, one layer at a time. Measure exactly 4-1/2 cups prepared blueberries into 6- or 8-qt. saucepot. Stir in lemon juice.
• Stir sugar into prepared blueberries in saucepot. Add butter to reduce foaming. Bring to full rolling boil (a boil that doesn't stop bubbling when stirred) on high heat, stirring constantly. Stir in pectin. Return to full rolling boil and boil exactly 1 min., stirring constantly. Remove from heat. Skim off any foam with metal spoon.
• Ladle immediately 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 middles of lids with finger. (If lids spring back, lids are not sealed and refrigeration is necessary.)
