CERTO® BOYSENBERRY 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 of the pulp through a sieve to remove some of the seeds, if desired.) Measure exactly 4 cups prepared fruit into 6- or 8-qt. saucepot.
• Stir in sugar. 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. 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 a 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.)

BOYSENBERRY JAM

Steps:

• Begin by setting up your cooking area for a batch of Rudy's Original boysenberry jam. Place the 8 quart stock pot on the stove. Setup your canner with the jar rack placed in the bottom of the pot. Setup a cooling rack for the jam jars. Line up your jars and lids. Set out the cooking and canning tools including the thermometer, potato masher, canning kettle, jar lifter, funnel and scoop.
• Juice 1 to 2 lemons. For best resuts, use regular lemons. This assures a good set of your jam. Meyer or seedless lemons do not give good results. Optional: The day before cooking, squeeze lemon juice and leave seeds in the juice, allowing them to soak. This releases extra flavorless pectin from the lemon seeds. Strain out the seeds just before adding to the jam mixture.
• Measure frozen boysenberries and place them in the stock pot. Measure organic sugar and lemon juice and set them aside.
• Thaw boysenberries in the stock pot on low heat until juices begin to flow.
• Mash softened berries with a potato masher.
• Adjust the heat under the stock pot to medium.
• Add lemon juice and stir.Gradually add sugar, stirring it in after each addition, mixing until all granules have melted, 4 to 5 minutes. This lengthens and strengthens pectin strands for a good jam set.
• Fill the canning kettle with water, place the jar rack in the bottom, cover it with a lid and turn it on in preparation to place your jam-filled jars into the boiling water bath when they are ready.
• Cook your jam batch, stirring frequently, while increasing the temperature, bringing it to a high simmer to low boil. If the jam begins to splatter, turn the heat down slightly. Continue to cook and stir until the temperature reaches 219 degrees on the candy thermometer, taking care not to burn or overcook. This will take about 25 to 30 minutes. The foam should have disappeared and the whole jam mixture will take on a more coagulated look, with a slightly dull skin.
• In the absence of a candy thermometer, a "just to be sure it's ready" doneness test can be used. I like the frozen plate test: freeze several ceramic plates prior to cooking. When the jam begins to coagulate in the pan during stirring, and foam has disappeared, take out a frozen plate and use a spoon to drop a thin puddle onto the plate. Wait 5 seconds, then draw your finger through the puddle. If the finger line doesn't fill back in with jam, your batch is ready! If it fills back in, covering the plate again, cook your jam batch for about three more minutes and try the finger line test again on a new frozen plate. Keep up this procedure until the finger line passes the test!
• Using a canning scoop and canning funnel, pour hot jam into jars. Fill within ¼" from the top of each jar. Wipe the rims of each jar to remove any spilled jam. Place the lid and ring on each jar as soon as you fill them. Screw the lids down tightly.
• Process jars in a boiling water bath: use a canning jar lifter to place jars into the bath. Bring the canner back to a rolling boil and process for 5 to 7 minutes. When you are ready to remove the jars from the water bath, turn down the heat and let the water calm down. This will help prevent getting spashed and burned from the boiling water. Lift out the jars and place them on a cooling rack allowing at least 2" space between jars. Increase the heat and repeat the hot bath canning process until all jars are on the cooling rack.
• For a good set, let the jars cool without moving for 24 hours.

BOYSENBERRY JAM

Steps:

• Wash berries gently in a colander and remove any leaves and stems. Drain.
• Heat to boiling in a large pan over high heat. Once the berries are boiling, begin to add the sugar in a slow steady stream so the berries don't go off the boil.
• Once the sugar is added, boil the pulp on the highest heat for 30 minutes. You must keep stirring constantly so that it doesn't catch and burn on the bottom.
• After 30 minutes at a hard boil, it should be noticeably thicker. Test for set by dropping a teaspoon full on a cold plate. After cooling a few minutes, you'll know if it is thick enough. Remember it will keep thickening as you do the test and setting as it cools.
• Remove it from the heat and add the juice (just to be sure it sets) and butter. Allow to cool for 10 minutes before pouring into hot sterilized jars. Place the lids on at once.

MCP BOYSENBERRY FREEZER JAM

Steps:

• Rinse clean plastic containers and lids with boiling water. Dry thoroughly.
• Crush boysenberries thoroughly, one layer at a time. Sieve half of the berries to remove seeds, if desired. Measure exactly 3 cups prepared fruit into large bowl. Add lemon juice; mix well.
• Stir pectin into prepared fruit in bowl. Let stand 30 min., stirring every 5 min. Gradually add sugar, stirring after each addition until well blended. Stir additional 3 min. or until most of the sugar is dissolved and no longer grainy. (A few sugar crystals may remain.)
• Fill all containers immediately to within 1/2 inch of tops. Wipe off top edges of containers; immediately cover with lids. Let stand at room temperature 24 hours. Jam is now ready to use. Store in refrigerator up to 3 weeks or freeze extra containers up to 1 year. If frozen, thaw in refrigerator before using.
