Plum Vanilla Jam Recipes

Steps:

• Start with our step-by-step canning how-to.
• Put the plums, sugar, vanilla beans and cinnamon sticks in a large, wide saucepan. Squeeze the lemon juice through a strainer into the pan. Cook over medium-high heat, stirring occasionally, until the sugar dissolves and the mixture boils, about 10 minutes.
• Reduce the heat to medium and continue to cook, stirring occasionally, until a candy or deep-fry thermometer registers 220 degrees F, about 30 minutes. (To be sure that the mixture has reached the gel point, spoon some onto a chilled plate and put in the freezer until cool. The liquid should set; if not, continue to cook and retest after a few more minutes.) Remove the pan from the heat and let cool 30 minutes.
• Meanwhile, sterilize four 8-ounce canning jars and lids.
• Return the plum mixture to medium-high heat. Bring to a boil, stirring, then add the plumcots. Reduce the heat to medium and simmer until the plumcots are tender, about 5 minutes. Discard the cinnamon sticks.
• Fill the jars with the plum mixture, leaving 1/2 inch headspace, then seal and process.

Steps:

• Bring all ingredients to a boil in a large stockpot, mashing with a potato masher. Cook, stirring frequently, until mixture is the consistency of very thick honey, 5 to 10 minutes. Remove plum skin if desired. Discard vanilla bean and zest. Do not strain; jam should be chunky.

Steps:

• In a large covered saucepan, bring plums, agave and vanilla bean to a boil.
• Lower heat, uncover pot and simmer 15 minutes, until plums are dissolved (though skins will remain).
• Cook 10 more minutes to reduce mixture, then stir in stevia.
• Remove vanilla bean, place plum mixture in blender and puree on highest setting.
• Transfer mixture back to pot and reheat on stove.
• In a small bowl, combine arrowroot powder and 1 tablespoon water to make a slurry.
• Bring plum mixture to a boil, then add arrowroot slurry, stirring continuously, until incorporated.
• Remove from heat, cool and transfer to mason jars.
• Store in refrigerator for up to one week.

Steps:

• Bring all ingredients to a boil in a large pot, mashing with a potato masher.
• Cook, stirring frequently, until mixture is the consistency of very thick honey, about 5 to 10 minutes.
• Remove plum skin if desired. Discard vanilla bean and zest. Do not strain; jam should be chunky.
• Refrigerate in an airtight container up to 1 month.

Steps:

• In large non-aluminum kettle, combine plums, water, and lemon juice. Bring mixture to boiling over high heat, stirring constantly. Reduce heat to low and cook, covered, 10 minutes or until soft, stirring occasionally. Mixture should have reduced to about 4 1/2 cups.
• Add sugar and heat mixture to full, rapid boiling over high heat, stirring constantly. Stir in pectin; return to full, rapid boiling and boil exactly 1 minute, stirring constantly. Remove from heat. Set aside 1 minute and skim off any foam that has formed.
• Meanwhile, sterilize 8 half-pint jars or jelly glasses and the necessary lids, and bands, according to manufacturer's directions. Divide jam among sterilized jars, leaving 1/8-inch space at top of jar. Wipe rims of jars to remove any jam and seal with lids and bands.
• Process jars in boiling water for 5 minutes. Remove jars, label, and store in cool, dry place

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.
