Plum Raspberry Jam Recipes

PLUM & RASPBERRY JAM

Steps:

• Tip the sugar into a heavy preserving pan or flameproof dish with the plums, lemon juice and half the raspberries. Heat until the sugar has dissolved, then bring to the boil and simmer for a few mins until the plums are tender. Add the rest of the raspberries to the pan.
• Place a jam thermometer in the pan, bring to the boil, then cook over a high heat until the temperature reaches 104C. Alternatively, put a small plate in the fridge or freezer until really cold. Once the jam has been boiling for 10 mins and looks thick and syrupy, turn off the heat and pour a spoonful onto the plate. The jam is ready when it wrinkles as you push it with your finger; be careful not to burn yourself. If the jam is not ready, boil for another 3 mins, then repeat test as above, until it is ready.
• Allow to cool for about 5 mins. Skim the surface of any scum and pack into warm sterilised jars (see tip below). Cover with wax discs and lids. Will keep in the fridge or a cold larder for up to 6 months.

RASPBERRY PLUM JAM

Steps:

• Combine the raspberries, sliced plums, sugar, lemon juice, and orange zest in a large heavy-bottomed pot. Place over medium high heat and stir frequently as the sugar dissolves and the fruit begins to release its juices.
• Continue to cook, stirring frequently as the jam simmers and thickens. Skim any foam off of the surface with a spoon.
• (Optional) While the jam is simmering, remove plum skins with a spoon. It is slightly tedious but I prefer the texture of the jam without the skins.
• (Optional) If you prefer fewer raspberry seeds, simply place a mesh strainer over the pot. Ladle ⅓-½ of the mixture into the strainer and push it through with a spatula back into the pot. Discard raspberry seeds.
• Once the jam is reduced and thickened (see tip above), remove from heat and ladle jam into sterilized jars. Top with a lid and screw on with a ring.
• Process jars in a water bath for 10 minutes (15 minutes for 5,000+ ft elevation). Remove from water bath and let cool. Check that lids have sealed by pressing down into the center of each one. It should not move.
• Store jam in a cool dry place like a pantry and consume within 1 year.

RED RASPBERRY-ORANGE JAM

Steps:

• Inspect 7 half-pint 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.
• Add raspberries to a blender or food processor; blend until smooth. Pour into a large saucepan.
• Cut off orange zest and finely chop. Add to the saucepan with the raspberries. Segment oranges and remove all the white pith, seeds, and fibrous membranes. Cut orange filets into small pieces; you should have 2 cups. Combine orange pieces with lemon juice in a bowl and mix. Add orange pieces and 1/4 cup sugar to the saucepan with the raspberries.
• Stir in pectin and slowly bring to a full rolling boil. Add remaining sugar and stir to dissolve. Return to a full rolling boil on high heat and boil for exactly 1 minute, stirring constantly. Skim off any foam with a ladle or a large spoon.
• Remove from heat and ladle jam into the prepared jars, filling to within 1/4 inch of the top. 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 spills. Top with lids and tightly screw on rings.
• 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 10 minutes.
• Remove the jars from the stockpot and place onto a cloth-covered or wood surface, several inches apart. Let rest for 24 hours without moving the jars. Gently 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.

PLUM JAM

Steps:

• Place the plums and water into a large pot, and bring to a boil. Reduce heat to medium-low, cover, and simmer for 5 minutes. Stir in the sugar, and add butter to reduce foaming, if needed. Bring the mixture to a full, rolling boil over high heat, stirring constantly, and then mix in the pectin quickly. Return the jam to a full boil, and boil for 1 minute, stirring constantly. Remove from heat, and skim off and discard any foam.
• Sterilize the jars and lids in boiling water for at least 5 minutes. Pack the plum jam into the hot, sterilized jars, filling the jars to within 1/8 inch of the top. Run a knife or a thin spatula around the insides of the jars after they have been filled to remove any air bubbles. Wipe the rims of the jars with a moist paper towel to remove any food residue. Top with lids, and screw on rings.
• Place a rack in the bottom of a large stockpot and fill halfway with water. Bring to a boil over high heat, then carefully lower the jars into the pot using a holder. Leave a 2 inch space between the jars. Pour in more boiling water if necessary until the water level is at least 1 inch above the tops of the jars. Bring the water to a full boil, cover the pot, and process for 10 minutes.
• Remove the jars from the stockpot and place onto a cloth-covered or wood surface, several inches apart, until cool. Once cool, press the top of each lid with a finger, ensuring that the seal is tight (lid does not move up or down at all). Store in a cool, dark area. Refrigerate opened jars for up to 3 weeks.

OLD-FASHIONED RASPBERRY JAM

Steps:

• 1. Place sugar in an ovenproof shallow pan and warm in a 250°F (120°C) oven for 15 minutes. (Warm sugar dissolves better.)
• 2. Place berries in a large stainless steel or enamel saucepan. Bring to a full boil over high heat, mashing berries with a potato masher as they heat. Boil hard for 1 minute, stirring constantly.
• 3. Add warm sugar, return to a boil, and boil until mixture will form a gel (see tips, below), about 5 minutes.
• 4. Ladle into sterilized jars and process as directed for Shorter Time Processing Procedure .
• Tip: To make a small boiling-water canner, tie several screw bands together with string or use a small round cake rack in the bottom of a large covered Dutch oven. Be sure the pan is high enough for 2 inches (5 cm) of water to cover the jars when they are sitting on the rack.

PLUM RASPBERRY JAM

Steps:

• Fill up canner with water and bring to a simmer.
• Meanwhile prepare jam, I use a food processor for plums and pulse to chop, do not puree, you still want little bits of fruit.
• In a large saucepan over med-high heat bring plums and sugar to a boil.
• Boil for 20 minutes, stirring often and skimming off any foam.
• After 20 minutes add jello, stir 2 min and until completely dissolved.
• Ladle quickly into sterilized hot jars; filling to within 1/4-1/2" of tops.
• With a clean damp towel wipe jar threads and rims.
• Place heated lids (lids that have been placed in simmering water for 1-2 minutes) on jars and tighten rings.
• Place jars on elevated rack in canner, lower rack into water (water must cover jars by 1-2") add BOILING water if needed.
• Cover bring water to a gentle boil and process for about 10 minutes.
• Remove jars and place upright on a towel to cool undisturbed completely (at least 24 hrs).
• After jars cool, check seals by pressing middle of lid with finger, if the lid springs back it did not seal, store unsealed jars in fridge and use up soon.
• Store unopened jams in a cool, dry, dark place.

PLUM-ROSEMARY JAM

Steps:

• Combine the plums, sugar and 1 tablespoon lemon juice in a medium saucepan or Dutch oven. Toss well and let stand until the sugar dissolves and the mixture is juicy, about 20 minutes.
• Wrap the rosemary sprig in a square of cheesecloth; tie closed. Add to the pan and bring to a boil over medium-high heat. Reduce the heat to maintain a simmer; cook, stirring occasionally and skimming off any foam, until thickened and the fruit is broken down, 30 to 35 minutes. Gently mash any large plum chunks with a potato masher or rubber spatula. Discard the rosemary. Stir in the remaining 1 tablespoon lemon juice. Remove from the heat and let the jam cool to room temperature, stirring occasionally, about 1 hour.
• Transfer the jam to a jar or other airtight container. Refrigerate until cold and fully jelled, at least 2 hours. Store in the refrigerator for up to 2 weeks.

PLUM-STRAWBERRY JAM

Steps:

• In a large pot or a Dutch oven, toss the strawberries and plums with the sugar. Let stand for at least 1 hour, tossing occasionally to encourage the fruits to release their juices.
• Bring the mixture to a boil over medium-high heat, then decrease the heat to medium-low to maintain a gentle simmer. Cook, stirring occasionally to make sure the mixture is not burning on the bottom, until the jam reaches the jelling point (use the wrinkle test, page 256, to judge when it's done).
• Ladle the jam into clean jars. Cover tightly, let cool, and refrigerate.
• Storage
• The jam will keep for at least 6 months in the refrigerator.

PLUM, RASPBERRY JAM & CARDAMOM CRUMBLE SQUARES

Steps:

• Butter and line a 30 x 20cm baking tin with baking parchment, leaving an overhang so you can lift out the traybake later, then butter the parchment. Heat the oven to 180C/160C fan/gas 4.
• To make the pastry, put all the ingredients, except the vanilla, into a food processor and blitz until the mixture resembles breadcrumbs. Add a couple of teaspoons of very cold water and the vanilla, then blitz again. The mixture should come together into a ball. If it doesn't, add a little more cold water and blitz again. Press into the tin using your fingers and the back of a large spoon, then bake in the oven for 15-18 mins until pale golden. Leave to cool for 15 mins.
• Stir the cardamom seeds and the lemon juice into the jam until smooth. Spread the jam over the pastry base, leaving a 2cm border all the way round. Cut each plum half into 1cm slices. Lay these in rows, overlapping, on top of the jam.
• To make the crumble, put the flour, ground almonds, butter, sugar and lemon zest into a food processor (you don't need to wash it out first), and blitz until the mixture looks like breadcrumbs. Tip this over the plums and scatter the flaked almonds on top. Bake for about 35-40 mins until the top is golden and the plums are tender. Leave to cool completely in the tin.
• Carefully lift the traybake out of the tin onto your work surface using the baking parchment. Leave for a few hours so the fruit can settle. Cut into squares or rectangles, then sift some icing sugar over the top, if you like.

HOMEMADE BLACKBERRY PLUM JAM

Steps:

• Prepare the boiling water canner before starting to cook your jam. (Fill the canner/stockpot at least half full of enough clean, warm water so the level will be at least 1" over the top of the filled jars once they're added).
• Wash, pit and chop plums w/ skins.
• Wash and crush blackberries w/ potato masher.
• Place plums and crushed blackberries in large pot.
• Add pectin a little at a time to plums and berries, stirring constantly.
• Heat on high stirring constantly until mixture comes to a FULL boil.
• Add sugar ALL at once, stirring.

• Skim off foam, if present.
• Place in sterilized, hot jars, leaving 1/4" headspace.
• Wipe edges of jars with clean cloth, place lids and screw on bands fingertip-tight.
• Process in a boiling water bath for ten minutes at sea level (over 1000 feet, add one minute of processing for each 1000 feet in altitude).
• Remove from water and place jars on a cloth-protected counter or cooling rack to cool undisturbed for 24 hours.
• Remove rings from sealed jars and store; put any unsealed jars in the refrigerator and use first.
