Yellow Plum Jam Recipes

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.

Steps:

• Bring boiling-water canner, half full with water, to simmer. Wash jars and screw bands in hot soapy water; rinse with warm water. Pour boiling water over flat lids in saucepan off the heat. Let stand in hot water until ready to use. Drain well before filling.
• Pit plums. Do not peel. Finely chop or grind fruit; place in saucepan. Add water. Bring to boil. Reduce heat; cover and simmer 5 min. Measure exactly 6 cups prepared fruit into 6- or 8-qt. saucepot.
• Stir pectin into fruit in saucepot. Add butter to reduce foaming. Bring mixture to full rolling boil (a boil that doesn't stop bubbling when stirred) on high heat, stirring constantly. Stir in sugar. Return to full rolling boil and boil exactly 1 min., stirring constantly. Remove from heat. Skim off any foam with metal spoon.
• Ladle immediately into prepared jars, filling to within 1/4 inch of tops. Wipe jar rims and threads. Cover with two-piece lids. Screw bands tightly. Place jars on elevated rack in canner. Lower rack into canner. (Water must cover jars by 1 to 2 inches. Add boiling water, if needed.) Cover; bring water to gentle boil. Process 10 min. Remove jars and place upright on a towel to cool completely. After jars cool, check seals by pressing middle of lids with finger. (If lids spring back, lids are not sealed and refrigeration is necessary.)

Steps:

• Combine all ingredients and bring to boil slowly, stirring occasionally, until sugar is dissolved. Cook quickly until jelly point (approximate 13 - 20 minutes) stirring frequently to prevent sticking.
• Pour into sterilized jars.

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:

• Bring boiling-water canner, half full with water, to simmer. Wash jars and screw bands in hot soapy water; rinse with warm water. Pour boiling water over flat lids in saucepan off the heat. Let stand in hot water until ready to use. Drain jars well before filling.
• Remove and discard pits from plums. Finely chop fruit. Measure exactly 5-3/4 cups prepared fruit into 6- or 8-qt. saucepot. Add lemon juice; mix well.
• Stir pectin into prepared fruit in stockpot. Add butter to reduce foaming. Bring mixture to full rolling boil (a boil that doesn't stop bubbling when stirred) on high heat, stirring constantly. Stir in sugar. Return to full rolling boil and boil exactly 4 min., stirring constantly. Remove from heat. Skim off any foam with metal spoon.
• Ladle immediately into prepared jars, filling to within 1/4 inch of tops. Wipe jar rims and threads. Cover with two-piece lids. Screw bands tightly. Place jars on elevated rack in canner. Lower rack into canner. (Water must cover jars by 1 to 2 inches. Add boiling water, if necessary.) Cover; bring water to gentle boil. Process 10 min. Remove jars and place upright on towel to cool completely. After jars cool, check seals by pressing middle of lids with finger. (If lids springs back, lids are not sealed and refrigeration is necessary.) Let prepared jars stand at room temperature 24 hours. Store unopened jams and jellies in cool, dry, dark place up to 1 year. Refrigerate opened jams and jellies up to 3 weeks.

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.

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.
