Fresh Strawberry Jam For Canning Recipes

Steps:

• Combine the sugar, lemon zest, and lemon juice in a small saucepan and cook over very low heat for 10 minutes, until the sugar is dissolved. Add the strawberries and continue to cook over very low heat for 20 minutes, until the strawberries release some of their juices and the mixture boils slowly. Cook until a small amount of the juice gels on a very cold plate. (I keep one in the freezer.) Pour carefully into 2 pint canning jars and either seal or keep refrigerated. Use immediately, or follow proper canning guidelines below.
• Sterilizing Tips:
• Jars should be made from glass and free of any chips or cracks. Preserving or canning jars are topped with a glass, plastic, or metal lid, which has a rubber seal. Two piece lids are best for canning, as they vacuum seal when processed.
• To sterilize jars, before filling with jams, pickles, or preserves, wash jars and lids with hot, soapy water. Rinse well and arrange jars and lids open sides up, without touching, on a tray. Leave in a preheated 175 degree F oven for 25 minutes. Or, boil the jars and lids in a large saucepan, covered with water, for 15 minutes.
• Use tongs when handling the hot sterilized jars, to move them from either boiling water or the oven. Be sure the tongs are sterilized too, by dipping the ends in boiling water for a few minutes.
• As a rule, hot preserves go into hot jars and cold preserves go into cold jars. All items used in the process of making jams, jellies, and preserves must be clean. This includes any towels used, and especially your hands.
• After the jars are sterilized, you can preserve the food. It is important to follow any canning and processing instructions included in the recipe and refer to USDA guidelines about the sterilization of canned products.

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.

Steps:

• Place chopped apples, lemon, and water in a saucepan. Bring to a boil over high heat; reduce heat to medium. Cover and cook, stirring occasionally, until fruit is very soft and collapsed, about 30 minutes. Remove from heat. Strain through a fine sieve into a bowl to separate the liquid from the pulp and seeds. Press with the back of a wooden spoon or spatula to extract as much liquid as possible. Discard pulp and seeds. You should have about 1 1/2 cups pectin puree. A bit more or less will work fine.
• Place hulled strawberries in the bowl of a food processor. Pulse until berries are pureed, about 1 minute. Transfer to a saucepan. Add strained pectin puree to strawberries. Stir in 1 cup sugar. Bring mixture to a simmer over medium-high heat. Reduce heat to medium; simmer for about 15 minutes. Skim off foam. Adjust heat, if necessary, to ensure mixture is always simmering without boiling over. Stir in remaining 1 1/4 cup sugar.
• Cook, stirring often, until mixture reaches 220 degrees F (105 degrees C), 50 to 60 minutes. Remove from heat. Whisk in lemon juice.
• Ladle into sterilized canning jars while still hot. Allow to cool to room temperature uncovered. Cover and refrigerate 1 or 2 days before serving to allow sugar and pectin to thicken up the jam.

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.
