Best 7 Rhubarb Plum Jam Recipes

RHUBARB-PLUM JAM

Steps:

• Combine rhubarb, plums, sugar, orange juice, water, and orange zest in a saucepan over medium heat; bring to a boil. Reduce heat to medium-low and cook, stirring occasionally, until thick, about 45 minutes.
• Meanwhile, inspect 6 pint-sized jars for cracks and rings for rust, discarding any defective ones. Immerse in simmering water until jam is ready. Wash new, unused lids and rings in warm soapy water.
• Place a rack in the bottom of a large stockpot and fill halfway with water. Bring to a boil.
• Pack jam into hot, sterilized jars, filling to within 1/4 inch of the top. Run a clean knife or thin spatula around the insides of the jars to remove any air bubbles. Wipe rims with a moist paper towel to remove any residue. Top with lids and screw rings on tightly.
• Lower jars 2 inches apart into the boiling water using a holder. Pour in more boiling water to cover jars by at least 1 inch. Bring to a rolling boil, cover, and process for 5 minutes.
• Remove the jars from the stockpot and let rest, several inches apart, for 12 to 24 hours. Press the center of each lid with a finger to ensure the lid does not move up or down. Remove the rings for storage and store in a cool, dark area.

PLUM-ROSEMARY JAM

Steps:

• Combine the plums, sugar and 1 tablespoon lemon juice in a medium saucepan or Dutch oven. Toss well and let stand until the sugar dissolves and the mixture is juicy, about 20 minutes.
• Wrap the rosemary sprig in a square of cheesecloth; tie closed. Add to the pan and bring to a boil over medium-high heat. Reduce the heat to maintain a simmer; cook, stirring occasionally and skimming off any foam, until thickened and the fruit is broken down, 30 to 35 minutes. Gently mash any large plum chunks with a potato masher or rubber spatula. Discard the rosemary. Stir in the remaining 1 tablespoon lemon juice. Remove from the heat and let the jam cool to room temperature, stirring occasionally, about 1 hour.
• Transfer the jam to a jar or other airtight container. Refrigerate until cold and fully jelled, at least 2 hours. Store in the refrigerator for up to 2 weeks.

STRAWBERRY-RHUBARB JAM

Steps:

• Toss the rhubarb, strawberries, sugar, lemon zest and juice and 3/4 teaspoon salt in a large saucepan to combine, then mash slightly to release some of the berry juice. Set aside for 10 minutes to allow the mixture 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. (See Cook's Note for flavor additions.) Bring the mixture to a boil and then reduce the heat to medium low, stirring frequently. Continue to cook until the jam becomes thick and syrupy, about 1 1/2 hours. 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 the jam. If the jam holds its shape and thickness, 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 for up to 6 months.

RHUBARB JAM

Steps:

• Cut rhubarb into 3 cm chunks
• Put rhubarb, sugar, and vanilla pods into a frying at low heat. When sugar dissolves, add lemon juice and put at higher heat for about 10 min.

PLUM JAM

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.

HOMEMADE BLACKBERRY PLUM JAM

Steps:

• Prepare the boiling water canner before starting to cook your jam. (Fill the canner/stockpot at least half full of enough clean, warm water so the level will be at least 1" over the top of the filled jars once they're added).
• Wash, pit and chop plums w/ skins.
• Wash and crush blackberries w/ potato masher.
• Place plums and crushed blackberries in large pot.
• Add pectin a little at a time to plums and berries, stirring constantly.

• Wipe edges of jars with clean cloth, place lids and screw on bands fingertip-tight.
• Process in a boiling water bath for ten minutes at sea level (over 1000 feet, add one minute of processing for each 1000 feet in altitude).
• Remove from water and place jars on a cloth-protected counter or cooling rack to cool undisturbed for 24 hours.
• Remove rings from sealed jars and store; put any unsealed jars in the refrigerator and use first.
