Plum Strawberry Jam Recipes

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:

• Dice 1 pound red plums; toss with 1 pound quartered strawberries, 3/4 cup sugar, 1 teaspoon vanilla extract, 1/2 teaspoon cinnamon and the juice of 1 lemon in a bowl. Cover and let stand 2 to 6 hours. Transfer to a large skillet. Add 1/3 cup honey; cook over medium-high heat, stirring occasionally, until the mixture is thick and registers 220 degrees F on a candy thermometer, about 30 minutes. Fill sterilized jars, leaving a 1/2-inch headspace, then seal and process for 15 minutes.
• TIP: This jam is delicious with butter on a crusty baguette or drizzled over vanilla ice cream.

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.

Steps:

• In a Dutch oven, combine the plums, raspberries, sugar and lemon juice. Bring to a full rolling boil over high heat, stirring constantly. Stir in pectin. Continue to boil 1 minute, stirring constantly. , Remove from heat; skim off foam. Ladle hot mixture into six hot pint jars, leaving 1/4-in. headspace. Remove air bubbles and adjust headspace, if necessary, by adding hot mixture. Wipe rims. Center lids on jars; screw on bands until fingertip tight. , Place jars into canner with simmering water, ensuring that they are completely covered with water. Bring to a boil; process for 10 minutes. Remove jars and cool.

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:

• Stir together plums, sugar, and 1/4 teaspoon salt in a large heavy-bottomed pot. Bring to a boil, stirring until sugar is dissolved and mashing plums with a potato masher. Add lemon juice; continue to boil, stirring frequently, until bubbles slow, chunks of fruit show at top, and mixture clings to a spoon but falls off in clumps, 10 to 12 minutes. Skim foam from top.
• Ladle jam into clean containers, leaving 3/4 inch of headroom. Let cool completely. Cover, label, and refrigerate up to 1 month, or freeze up to 1 year.

Steps:

• Crush strawberries and measure 4-1/2 cups berries into a large saucepan. Stir in pectin and bring to a rolling boil over high heat, stirring frequently. Add sugar and return to a rolling boil. Boil for 1 minute, stirring constantly. , Remove from heat and skim off foam. Carefully ladle hot mixture into hot half-pint jars, leaving 1/4-in. headspace. Remove air bubbles; wipe rims and adjust lids. Process for 10 minutes in a boiling-water canner.

Steps:

• Sterilise the jars and any other equipment before you start (see tip). Put a couple of saucers in the freezer, as you'll need these for testing whether the jam is ready later (or use a sugar thermometer). Put the plums in a preserving pan and add 200ml water. Bring to a simmer, and cook for about 10 mins until the plums are tender but not falling apart. Add the sugar, ground cinnamon and lemon juice, then let the sugar dissolve slowly, without boiling. This will take about 10 mins.
• Increase the heat and bring the jam to a full rolling boil. After about 5 mins, spoon a little jam onto a cold saucer. Wait a few seconds, then push the jam with your fingertip. If it wrinkles, the jam is ready. If not, cook for a few mins more and test again, with another cold saucer. If you have a sugar thermometer, it will read 105C when ready.
• Take the jam off the heat and add the cinnamon sticks (if using) and the knob of butter. The cinnamon will look pretty in the jars and the butter will disperse any scum. Let the jam cool for 15 mins, which will prevent the lumps of fruit sinking to the bottom of the jars. Ladle into hot jars, seal and leave to cool. Will keep for 1 year in a cool, dark place. Chill once opened.
