Blackberry Jam Recipe for Canning

This easy Homemade Blackberry Jam Recipe for canning is a sweet temptation that is easier to make than you might think!

Prep Time25 mins

Cook Time15 mins

Total Time40 mins

Course: Breakfast

Cuisine: American

Keyword: jam, preserves

Servings: 72 ounces {Nine 8 oz. Jars or Six 12 oz. jars}

Author: The Frugal Girls

Ingredients

• 5 cups Crushed Fresh Blackberries {you'll need approx. 8 cups Fresh Blackberries or approx. 7 six oz. containers}
• 7 cups Granulated {White} Sugar
• 1 packet Original Sure-Jell Premium Fruit Pectin {1.75 oz.}
• 2 tbsp. Lemon Juice
• 1/2 tsp. Butter

Instructions

• Wash jars, lids, and bands in hot soapy water, dry completely, then set bands aside.
• Simmer lids in warm water in saucepan until ready to place them on jars.
• Keep jars warm by simmering in hot water until ready to use. Do not boil.
• Fill 20 quart stock pot or your water bath canner with hot water, and place on stove over medium-high heat. {you'll need enough water to later cover your jars with at least 1 inch of water}
• Crush blackberries in large mixing bowl or shallow glass baking dish using hand masher until nice, smooth consistency.
• Transfer crushed blackberries to 8 quart stock pot. Add pectin, lemon juice and butter to pot, and stir constantly with wooden spoon over high heat, while bringing to a rolling boil.
• Once boiling, add sugar, return to rolling boil, then boil for 1 minute while stirring constantly.
• After 1 minute, remove foam from top of jam by skimming it off with a metal spoon.
• Then... one by one, remove a jar from hot water, transfer to a cookie sheet {this will catch any spills}, place regular mouth canning funnel on jar, and ladle in blackberry jam mixture leaving 1/4 inch empty head space at top of the jar. After filling, wipe off rim of lid and threads of jar with damp cloth.
• Continue until all jars have been filled.
• Remove warm lids from saucepan {magnetic lid lifters work like a charm}, and place one lid on each jar.
• Then screw one band on each jar just until snug {not overly tight}.
• Place filled jars on rack in 20 quart stock pot {or water bath canner}, then lower down into hot water. Make sure there is enough water in pot that there is at least 1 inch of water above the jars. If necessary, add more HOT water.
• Place lid on your pot, and bring to a gentle boil.
• Once water is boiling, set your timer for processing. Boiling time will vary depending on where you live... for altitude 0 - 1,000 feet boil 10 minutes, for 1,001 - 3,000 boil 15 minutes, for 3,001 - 6,000 boil 20 minutes, for 6,001 - 8,000 boil 25 minutes, and for 8,001+ boil 30 minutes.
• Once jars have finished boiling, turn off heat, remove the lid from the pot and let jars sit for 5 minutes before removing. After 5 minutes, lift up rack to elevated resting position, then carefully remove jars, one by one using a jar lifter, and transfer to folded towels on the counter to cool.
• The lids on the jars will begin to 'pop' into the sealed position, signifying the jam has been preserved.* {see notes} If any lids do not pop, transfer those to the refrigerator and use those up first.
• Homemade Blackberry Jam Shelf Life: Jars can be stored in your pantry, or a cool, dry cupboard for up to 1 year. Label the top of each lid with the type of jam and the date it was made. Remove bands when storing, and be sure to never stack jars on top of each other. Always inspect lids to ensure the seals are good before using. When ready to use, transfer a jar to your refrigerator, and use within 3 weeks. ENJOY!

Notes

*8 oz. jars are my favorite for jam, but 12 oz. jars can also be used.  However, you are more likely to notice fruit float with taller jars.  After lids have popped and sealed and the jam is still warm, if you notice any fruit float {a very common issue where the denser fruit will rise and the liquid will be more at the bottom of the jar}, carefully flip your jars over upside down for 1 hour, then gently flip them right side up for 1 hour, flip them upside down for another hour, then right side up until jars have cooled to room temperature. This will help reduce 'fruit float' and ensure the jam is more evenly distributed within the jar. This step can also be skipped, as it is unnecessary, and more of a cosmetic procedure. It's perfectly fine to eat with fruit float, after opening the jar for the first time, simply stir to combine and you're good to go.
