Plum Ginger Freezer Jam Recipes

PLUM AND GINGER JAM

Steps:

• Gather the ingredients.
• Halve the plums, remove the stone and place the plum halves into a large ceramic bowl. Save 10 to 12 plum stones and discard the rest.
• Sprinkle the plum halves with 4 tablespoons of the sugar.
• Cover with a tea cloth and put to one side for 2 hours at room temperature, or preferably overnight in the fridge if you have the time. After a few hours, you will see the sugar has melted and the plums have rendered up plenty of juice. When this happens it is time to make the jam.
• Place all the plums, the juices, the remaining sugar, and the ginger, if using, into a large, heavy-bottomed or preserving pan. Place over medium heat and stir until all the sugar has dissolved. Raise the heat until the jam begins to bubble and boil the mixture for approximately 10 minutes, stirring every 2 minutes to avoid the sugars sticking to the sides of the pan.
• Put a clean saucer or tea plate into the freezer.
• Crack the shells of the pits and remove the tiny kernels inside.
• Place the kernels in a teacup and cover with boiling water for 1 minute.
• Strain the kernels; the skin should come away from the kernel easily. Reserve.
• After the jam has boiled for 10 minutes, take the saucer or plate from the freezer, take a small spoonful of the jam and place onto the saucer. Pop it into the fridge for 5 minutes. Push the edge of the jam on the saucer and if it "wrinkles" the jam is ready. If not, continue to boil on high heat. Repeat the jam setting test until the jam shows "wrinkles" when pushed.
• Once the jam is ready, turn off the heat but do not remove from burner. Leave it to stand for approximately 10 minutes.
• Take your hot, sterilized jam jars one by one and, using a jug and a funnel, carefully fill to the neck of the jar.
• Once all the jars are filled, divide the kernels between the jars.
• Cover the surface of the jam in the jar with a wax disc-this will help prevent mold forming during storage. Seal the jar with a tight-fitting lid or a cellophane disc secured with an elastic band. Leave to cool.

BLACK PLUM & GINGER JAM (WITHOUT PECTIN)

Steps:

• Place the chopped plums, sugar, lemon juice, lemon zest, ginger and salt in a medium sauce pan over medium-high heat. Bring the mixture to a boil, stirring occasionally. Reduce the heat to medium-low. Simmer for 5 minutes, stirring occasionally.
• Strain the mixture through a fine mesh sieve over a bowl, pressing down on the solids to extract as much juice as possible. Reserve the solids.
• Return the strained juices to the sauce pan. Bring to a boil over medium-high heat, stirring frequently to avoid burning. Boil until a candy thermometer reads 220 degrees (the gel stage). Remove the pan from the heat. Stir in the reserved solids.
• Transfer the jam to sterile jars, or freeze whatever jam you don't intend to use right away.
• Enjoy!

PLUM-GINGER FREEZER JAM

Steps:

• Using a potato masher or fork, gently crush the plums in a large bowl to release some pulp and juices while keeping the fruit chunky. Toss with the sugar, then add the ginger and lemon zest and juice. Stir until the sugar dissolves. Measure the volume of your fruit mixture; you should have about 6 cups.
• If your package of pectin comes with calcium powder, stir 1/4 teaspoon of the calcium powder into 1/4 cup water to dissolve. Set aside. Place the 4 1/2 teaspoons pectin in a stand blender, or have it measured and ready if using an immersion blender. Bring 1 cup water to a boil, then pour it into the stand blender and blend. (If using an immersion blender, add the pectin to the saucepan and blend.) The mixture should become very smooth and look like a soft gel. Stir the pectin mixture into the fruit until evenly combined, then stir in 4 teaspoons of the calcium water, if using. The jam should thicken and be softly set. Add the salt, stir and taste. Adjust after tasting with more teaspoons of lemon juice, if necessary, for a good balance of sweet and tart.
• Transfer to clean airtight containers, cover and chill in the refrigerator for at least 24 hours and up to 2 weeks before serving. Or, store in the freezer for up to 3 months; defrost completely in the refrigerator before serving.

GINGERED PLUM JAM

Steps:

• Place all the ingredients in a heavy large pot; stir to combine.
• Attach a jelly thermometer to side of pan or place a small plate in freezer to chill for testing jam.
• Bring to a rolling boil over medium-high heat, adjusting heat as needed to maintain an even boil; boil for 15 minutes, stirring frequently.
• After 15 minutes of cooking check temperature on thermometer or test small portion of jam on chilled plate, return plate to freezer for 1 to 2 minutes, remove and run finger through sample. When the jam is set you can pull your finger through it and it doesn't run back together. During testing, remove jam from heat.
• As jam sets you will be able to see the bottom of the pot when stirring. The temperature should be about 221 degrees F.
• Pour the hot jam into 4 sterilized 8-ounce jars, carefully wiping jar rims; cover with lids and screw bands.
• Process in boiling water bath for 5 minutes, remove from water bath, allow to cool; check seal.

PLUM FREEZER JAM WITH CARDAMOM AND GINGER

Steps:

• Bring plums and 1 cup water to a boil in a medium saucepan, then reduce heat to low and simmer until plums begin to soften and liquid is reduced by about half, about 5 minutes.
• Meanwhile, finely grate ginger, then squeeze juice into a small bowl; discard pulp.
• Combine sugar and pectin in a large bowl. Add plum mixture, lemon juice, pepper, cardamom, and 1 tsp. ginger juice (discard any remaining juice), then stir constantly for about 3 minutes to activate pectin. Using a potato masher or fork, break up any large plum pieces, then let cool at least 30 minutes.
• Ladle jam into sterilized jars, leaving 1/2" from the top to allow for expansion. Cover and chill.
• Do Ahead
• Jam can be made and chilled for up to 2 weeks or frozen for up to 1 year.
