Strawberry Jam Recipe For Canning

Steps:

• Place a wire rack in a rimmed baking sheet or line it with a clean towel. (This is to prevent the jars from directly touching the surface.) Set aside.
• Sterilize eight 1/2-pint canning jars and lids. To sterilize jars using a boiling water canner or a large pot, place a rack (or often I will use a clean kitchen towel) on the bottom of the canner. Place the jars right-side-up on the rack and fill the jars and canner with enough water to cover the jars by at least 1 inch. Bring the water to a boil, then boil for 10 minutes (at altitudes less than 1,000 feet elevation; see Cook's Note). Using canning tongs, remove the jars from the canner one at a time, carefully pouring the water from the jars back into the canner. Let the jars air-dry upside-down on the prepared rack or towel and sit undisturbed until you're ready to fill them. The rings and rubber-lined lids must be sterilized, too. Place the new lids in a small saucepan, cover with water and bring to a gentle simmer. Very gently simmer for 10 minutes (taking care not to boil). Turn off the heat and keep the lids in the water until ready to use.
• Combine the strawberries, lemon juice and sugar in a heavy 6- to 8-quart non-reactive pot and stir well. Place over high heat and, stirring constantly, bring to a full boil with bubbles over the entire surface. Boil for 1 minute, stirring constantly. Remove from the heat and stir in the liquid pectin.
• For each jar, insert a canning funnel and carefully ladle in the jam, allowing at least 1/4 inch of headroom. Clean the rims of the jars with a clean, damp towel and tightly secure the lids.
• Place the canning rack in the canner and fill the pot with water; bring to a boil over high heat.
• Using tongs, place the jars on the rack in the canner. The water should cover the jars by at least 1 inch. Cover the canner. Return the water to a boil and boil gently for 5 minutes (at altitudes less than 1,000 feet elevation; see Cook's Note). Using tongs, transfer the jars to a towel to cool. If the seal works and fits properly, the metal lid will be slightly concave within 24 hours of processing. Store the unopened jars of jam at room temperature for up to 1 year. Once the jam is opened, store in the refrigerator for up to 1 month.

Steps:

• Place the mason jars in a large hot water bath canner (or pot). Cover with water and bring to a simmer. Simmer the center lids in separate saucepan full of water.
• Place the mashed strawberries and lemon juice in a separate pot. Stir in the pectin until dissolved. Bring the strawberries to a strong boil.
• Add the sugar (measure beforehand so you can add it all at once), and then return the mixture to a full (violent) boil that can't be stirred down. Boil hard for 1 minute 15 seconds. Skim foam off the top.
• Remove one jar at a time from the simmering water. Pour water back into the pot. Using a wide-mouth funnel, fill each jar with jam, being careful to keep the liquid/fruit ratio consistent. Fill the jars so that they have 1/4-inch of space at the top. Run a knife down the side of the jar to get rid of air bubbles. Wipe the rim of the jar with a wet cloth to remove any residue or stickiness.
• Remove the center lid from the simmering water and position it on top. Put screw bands on jars, but do not over tighten! Repeat with all the jars, and then place the jars on a canning rack and lower into the water. Place the lid on the canner, and then bring the water to a full boil. Boil hard for 10 to 12 minutes.
• Turn off the heat and allow the jars to remain in the hot water for an addition 5 minutes. Remove the jars from the water using a jar lifter, and allow them to sit undisturbed for 24 hours.
• After 24 hours, remove the screw bands and check the seal of the jars. The center lids should have no give whatsoever. If any seals are compromised, store those jars in the fridge. Otherwise, fill your pantry with your newly canned goodness.

Steps:

• In a large saucepan, bring strawberries up to a simmer over medium-low heat, mashing roughly with a potato masher or flat spoon.
• Add sugar and lemon juice, stir, and bring up to a simmer for 2 minutes.
• Add butter and bring to a vigorous boil, stirring often, and cook for 10 to 20 minutes, periodically measuring the viscosity of the jam by dabbing a spoonful onto a plate and tipping the plate.
• Once the jam slows its drip down the plate (it should no longer run like a syrup), remove from heat and skim off foam.
• Fill jars that have been washed, rinsed, dried and boiled in a pot of water for 3 minutes to 1/4 inch from the top.
• Fasten lids securely and boil jars in a vat of water (be sure jars are completely submerged) for 15 minutes.
• Remove jars with tongs and let cool upright.
• Check for secure seals on jars (lid should not spring when touched) and store in a cool place away from light for up to a year.
• Any jars that do not achieve a proper seal should be refrigerated.

Steps:

• Wash jars & screw bands in hot soapy water. Rinse well in warm water. Pour boiling water over flat lids in a pan off the heat. Let stand in hot water until ready to use. Drain well before using.
• Fill canner half full of water and bring to a simmer.
• Prepare berries by crushing 1 cup at a time using a potato masher.
• Measure exact amount of fruit into an 8qt. saucepan.
• Measure the exact amount of sugar into a separate bowl. (Do not reduce sugar or use sugar substitute. Look up no-sugar-needed recipes for those amounts.).
• Mix 1/4 cup of sugar from measured amount with Sure-Jell. (Make sure to use the pink box of less or no sugar needed pectin!).
• Stir sugar & pectin mixture into berries. Add 1/2 teaspoons butter to reduce foaming, if desired.
• Bring to a full rolling boil (a boil that does not stop bubbling when stirred) stirring constantly.
• Stir in sugar, quickly. Return mixture to a full rolling boil and boil exactly 1 minute, stirring constantly.
• Remove from heat. Skim foam from top with metal spoon.
• Ladle quickly into jars to within 1/8 inch of top.
• Wipe jars' rims and threads and top with two-piece lids.
• Place jars in water bath canner for 10 minutes, then remove from canner. Let cool completely before storing. Press on middle of the lid to make sure lids have sealed. If not, store in refrigerator.

Steps:

• Prepare the strawberries by wiping them with a piece of damp kitchen paper. (Wiping the strawberries rather than washing them ensures the fruit doesn't absorb lots of water - too much water and the jam won't set easily.) To hull the fruit, use a knife to cut a cone shape into the strawberry and remove the stem. Cut any large berries in half.
• Put the strawberries in a bowl and gently toss through the sugar. Leave uncovered at room temperature for 12 hrs or overnight. This process helps the sugar to dissolve, ensures the fruit doesn't disintegrate too much and helps to keep its vibrant colour.
• Before starting the jam, put 2 saucers in the freezer. Tip the strawberry mixture into a preserving pan with the lemon juice. Set over a low heat and cook very gently. If any sugar remains on the sides of the pan, dip a pastry brush in hot water and brush the sugar away.
• When you can no longer feel any grains of sugar remaining, turn up the heat to start bubbling the jam and bringing it to the boil. (The sugar must be completely dissolved before increasing the heat, otherwise it will be difficult for the jam to set, and it may contain crystallised lumps of sugar.)
• Boil hard for 5-10 mins until the jam has reached 105C on a preserving or digital thermometer, then turn off the heat. If you don't have a thermometer, spoon a little jam onto one of the cold saucers. Leave for 30 secs, then push with your finger; if the jam wrinkles and doesn't flood to fill the gap, it is ready. If not, turn the heat back on and boil for 2 mins more, then turn off the heat and do the wrinkle test again. Repeat until ready.
• Use a spoon to skim any scum that has risen to the surface and discard this. Do this only once at the end, rather than constantly during the boiling stage, to reduce wastage.
• Add a knob of butter, if you like, to the finished jam, and stir in to melt. This will help to dissolve any remaining scum that you haven't managed to spoon off the top. Leave the jam to settle for 15 mins - this will ensure that the fruit stays suspended in the mixture and doesn't all float to the top of the jam jar. Meanwhile, sterilise your jars.
• Ladle into warm jars, filling to just below the rim. Place a wax disc on top of the jam (this prevents mildew forming), then cover with a lid or a cellophane circle and elastic band. Pop on a label (include the date), plus a pretty fabric top, if you like. The jam can be stored for up to 1 year in a cool, dry place. Refrigerate after opening.

Steps:

• In a wide bowl, crush strawberries in batches until you have 4 cups of mashed berry. In a heavy bottomed saucepan, mix together the strawberries, sugar, and lemon juice. Stir over low heat until the sugar is dissolved. Increase heat to high, and bring the mixture to a full rolling boil. Boil, stirring often, until the mixture reaches 220 degrees F (105 degrees C). Transfer to hot sterile jars, leaving 1/4 to 1/2 inch headspace, and seal. Process in a water bath. If the jam is going to be eaten right away, don't bother with processing, and just refrigerate.
