Strawberry Jam In A Slow Cooker 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:

• 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.
