Plum Raspberry Jam Recipes

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.

Steps:

• Toss the raspberries, sugar and lemon zest and juice in a medium saucepan to combine, then mash slightly to release some of the berry juice. Set aside for 10 minutes to allow the raspberries to macerate and the sugar to dissolve. Meanwhile, place a small plate in the freezer to chill; this will be used to test the doneness of the jam.
• Place the saucepan over medium-high heat. Bring the mixture to a boil and then reduce the heat to medium, stirring frequently. Continue to cook until the jam becomes thick and syrupy, about 25 minutes. To test doneness, place a small amount of the jam onto the chilled plate and freeze for 2 minutes. Drag your finger or spoon through it. If the jam holds its shape and thickness, the jam is done; remove from the heat. If it's runny, continue to cook and test again in 5-minute increments. Once the jam has reached the right consistency, transfer to jars and cool completely before storing, covered tightly. Jam will keep in the refrigerator up to 6 months.

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.

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.

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.
