Jostaberry Jam Recipes

STRAWBERRY JAM

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.

GOOSEBERRY JAM

Steps:

• First sterilise your jars by washing thoroughly in very hot soapy water. Rinse in very hot water then put on a baking sheet in a 140C/fan 120C/gas 1 oven until completely dry.
• Put the gooseberries, lemon juice and 400ml water in a large wide pan (use a preserving pan if you have one). Bring to the boil then simmer for 15 minutes until the fruit is very soft and pulpy. Put 2 or 3 small saucers in the freezer (these will be used to test the setting later on).
• Add the sugar and stir over a gentle heat for another 10 minutes until the sugar is completely dissolved. You don't want it to boil at this point as the sugar could crystallize. Once you can't feel or see any grains of sugar bring to the boil and boil hard for 10 minutes, skimming the surface as you go and stirring now and again to stop it catching. The jam will start to turn a pinky red hue as it cooks.
• Spoon a little jam onto a chilled saucer, leave to cool then run your finger through it. If it's ready it will wrinkle up. If this doesn't happen boil for another 5 minutes then keep testing and boiling until it does.
• Do a final skim on the finished jam then pour into the sterilised jars and seal. Store in a cool dark place - the jam will be good for up to 6 months. Keep in the fridge once opened.

GOOSEBERRY JAM

Steps:

• Remove blossom and stem ends from gooseberries. Force berries through food mill. Measure 4 cups of the berry mash into a large pot. Stir in the sugar. Bring to a full rolling boil over high heat, and boil hard for 1 minute, stirring constantly. Remove from heat, and stir in pectin at once. Skim off any foam with a large metal spoon.
• Sterilize jars and lids in boiling water for at least 10 minutes. Take turns with skimming foam, and stirring the berry mixture for 5 minutes to let it cool slightly. Ladle into hot sterile jars, leaving 1/4 inch headspace.
• Process in a boiling water bath for 10 minutes.

GOOSEBERRY JAM

Steps:

• Place a few small plates in the freezer. Put gooseberries and 1/4 cup water into a medium saucepan. Cover, and cook over medium heat, stirring halfway through, until berries are just beginning to soften, about 10 minutes.
• Stir in sugar, and mash berries against side of pan with the spoon. Cook, uncovered, stirring more frequently as jam thickens, until it is bubbling rapidly and the consistency of very loose jelly, about 30 minutes, skimming any foam that rises to surface. Remove from heat.
• Perform a gel test: Remove a plate from freezer, and drop a spoonful of jam on it. Return to freezer for 1 to 2 minutes, then nudge edge of jam with a finger. If jam is ready, it should hold its shape. If jam is too thin and spreads out, return to a boil, testing every minute, until done.
• Return jam to a boil before transferring to a jar. To seal and process, fill 3 hot, sterilized 4-ounce jars with hot jam, leaving 1/4 inch space in each jars neck. Wipe rims of jars with a clean, damp cloth; cover tightly with sterilized lids and screw tops. Transfer jars, using tongs or a jar clamp, to the rack of a large canning pot filled with hot water, being sure to keep jars upright at all times; cover with water by 2 inches. (Jars should be spaced 1 inch apart, and should not touch sides of pot.) Cover; bring to a boil. Process jars in gently boiling water for 5 minutes. Transfer to a wire rack; let cool 24 hours. Press down on each lid. If lid pops back, it is not sealed; refrigerate unsealed jars immediately, and use within 1 month.

JUMBLEBERRY JAM

Steps:

• Before you start, sterilise your jars and put a plate in the freezer to chill.
• Tip the berries, lemon juice and sugar into a preserving pan. Gently heat, stirring occasionally with a wooden spoon, until the sugar has melted and fruits are juicy.
• Bring to the boil and boil rapidly for 5 mins. Remove from the heat and drop a little of the mixture onto the chilled plate. Push your finger through it; it should wrinkle and have set like jam. If it doesn't, boil for 2 mins more, then test again and, if necessary, keep repeating until it's ready.
• The top of the jam may look like it has sediment on it, but if you stir it well as it cools, it should disappear. Allow to cool and settle for 10-15 mins before ladling into sterilised jars and sealing. The jam will keep unopened for 1 year but, once opened, store in the fridge.

JOSTABERRY JAM

Steps:

• Prepare jam as directed on Certo box.

SALMONBERRY JAM

Steps:

• Inspect seven 8-ounce jars for cracks and rings for rust, discarding any defective ones. Immerse in simmering water until jam is ready. Wash new, unused lids and rings in warm soapy water.
• Crush berries. Place 1/2 crushed fruit into sieve or cheesecloth to remove some seeds if desired. Transfer all berries to a large pot.
• Stir in sugar and bring mixture to a full rolling boil over high heat, stirring constantly. Quickly stir in pectin. Return to a full boil and boil for exactly 1 minute, stirring constantly. Remove from heat.
• Skim off any foam with metal spoon. Ladle quickly into the prepared jars, filling within 1/8 inch of tops. Run a clean knife or thin spatula around the insides of the jars to remove any air bubbles. Wipe rims with a moist paper towel to remove any residue. Top with lids and screw rings on tightly.
• Place a rack in the bottom of a large stockpot and fill halfway with water. Bring to a boil and lower jars 2 inches apart into the boiling water using a holder. Pour in more boiling water to cover jars by at least 1 inch. Bring to a rolling boil, cover, and process for 5 minutes.
• Remove the jars from the stockpot and let rest, several inches apart, for 24 hours. Press the center of each lid with a finger to ensure the lid does not move up or down. Remove the rings for storage and store in a cool, dark area for up to 1 year.
