Rhubarb Blackberry Jam Recipes

Steps:

• Place the sugar and cassis in a large (8-by-4-inch) heavy-bottomed saucepan. Add the rhubarb, blueberries, apple, and lemon zest and toss well to coat the fruit with the cassis and sugar. Cover the pot and cook over medium heat for 5 to 10 minutes, until there is a lot of liquid and it comes to a full boil. Lower the heat and cook uncovered at a low boil for 35 to 40 minutes, stirring occasionally, until the fruit has disintegrated and the mixture has thickened. (I test a little by putting some jam in a dish in the freezer to check the consistency when it cools.) If necessary, cook for another 5 minutes. Set aside to cool, then refrigerate.

Steps:

• The night before you make your jam, layer the blackberries and sugar together in a very large bowl, then cover and set aside at room temperature. This helps the sugar to start dissolving so you don't run the risk of over-cooking the fruit when you actually begin to make the jam. The next morning, give everything a quick stir, then set aside again until you are ready to start cooking.
• Before you start, put a small saucer in the freezer. Take a preserving pan or a large, wide-based pan (the wider and more open the pan, the faster the jam will be ready, so a preserving pan is really ideal) and tip the berries in, scraping out all the juices and any undissolved sugar. Stir in the lemon juice, then collect all the pips and secure them inside a tea-leaf strainer or piece of muslin before adding them to the pan (cooking the pips along with the fruit extracts the pectin they contain, helping your jam to set).
• Start the blackberries over a low heat until all the sugar is completely dissolved, then bring to the boil and simmer for 5 mins. Turn off the heat and spoon a little hot syrupy jam onto the chilled saucer. Once it's cool, push it with your finger. If it wrinkles a little, it's ready and has reached setting point. If it's too runny to wrinkle, return the pan to the heat and boil in 2 or 3-minute stages, removing the pan from the heat each time you do the saucer check, until the jam wrinkles.
• Skim off any excess scum, then stir in the knob of butter, if you want - this will help to dissolve any remaining scum. Leave the jam for 15 mins before ladling into sterilised jars - this allows the fruit to settle so it doesn't sink to the bottom. The jam will keep in a cool, dark place for at least 6 months. Refrigerate jars once opened.

Steps:

• Combine the rhubarb, sugar and blueberry pie filling in a large pot. Bring to a rolling boil over medium-high heat, and boil for 10 minutes longer. Stir in dry gelatin mix until dissolved. Transfer to sterile jars or freezer tubs, and cool. Freeze any jam you don't intend to use right away.

Steps:

• Put a small plate in the freezer. Put the rhubarb into a preserving pan or your largest saucepan with the sugar and halved vanilla pods. Heat gently, stirring, until all the sugar has dissolved, then squeeze in the lemon juice and increase the heat.
• Boil for about 10 mins, skimming off the scum as you go (the fruit should be soft). Test for setting point by spooning a little onto your chilled plate. After 1-2 mins, push your finger through the jam - if the surface wrinkles it is ready, if not, keep cooking for 2-min intervals, testing in between. (Or if you have a sugar thermometer it should reach 105C)
• Once the jam is ready, let it cool for about 15 mins before ladling into warm sterilised jars and sealing. Will keep for 6 months in a cool, dark place.

Steps:

• Combine rhubarb, sugar, raspberries, and lemon juice in a large pot. Let sit until sugar begins to dissolve, about 5 minutes. Bring to a boil; cook, stirring often, about 15 minutes. Add raspberry-flavored gelatin; stir until dissolved, 1 to 2 minutes. Remove jam from heat.
• Pack jam into hot, sterilized jars, filling to within 1/4 inch of the top. Wipe the rims of the jars with a moist paper towel to remove any 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 and place jars 2 inches apart into the water using a holder. Pour in more boiling water if necessary to bring the water level to at least 1 inch above the tops of the jars. Bring the water to a rolling 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 completely cool, about 2 hours. Press the top of each lid with a finger, ensuring that the seal is tight. Store in a cool, dark area.

Steps:

• In a large kettle, cook rhubarb and water over medium-high heat for 3-5 minutes or until rhubarb is tender. Add sugar. Bring to a boil; boil for 2 minutes. Stir in pie filling, blueberries and lemon juice. Return to a boil. Reduce heat; cook and stir for 10 minutes. Remove from heat; stir in gelatin until dissolved. Cool slightly. Pour into refrigerator containers. Cool to room temperature. Cover and refrigerate.

Steps:

• In a saucepan, combine the rhubarb, sugar, orange zest, orange juice and water. Bring to a boil, then cook over medium-low heat for 45 minutes, stirring occasionally, or until thick. It will thicken more as it cools.
• Ladle into hot sterile jars, and seal with lids and rings. Store opened jars in the refrigerator.

Steps:

• In a large bowl, add rhubarb and sugar; stir to coat evenly.
• Cover bowl, and place in the refrigerator overnight.
• The next morning, place rhubarb mixture in a large kettle.
• Cook over medium heat, stirring constantly; until mixture starts to boil.
• Lower heat just a bit, and cook for 12 minutes (stirring constantly).
• Remove from heat, add the gelatin; keep stirring for 1 minute.
• Add the can of pie filling; stir until mixed through.
• Return to stove. Start to cook over medium heat, stirring constantly; until mixture comes to a boil.
• Remove from heat, and carefully ladle into sterilized glass jars; cover with lids.
• Cool to room temperature, before storing in the refrigerator or freezer.

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.

Steps:

• Inspect four 4-ounce 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 strawberries in a large bowl and crush with a potato masher. Transfer to a 4-cup liquid measure and add enough rhubarb to reach the 4-cup mark.
• Pour fruit mixture into a large, heavy pot and sprinkle citric acid over top. Stir sugar and butter into the fruit mixture. Bring to a rolling boil, stirring constantly. Mix in pectin and return to a boil. Cook for 1 to 2 more minutes, then turn off heat and skim off any foam. Quickly mix in chopped basil until fully incorporated.
• Ladle 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.
• Place a rack in the bottom of a large stockpot and fill halfway with water. Bring to a boil and 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 10 minutes.
• Remove the jars from the stockpot and let sit 8 hours to overnight to completely seal; you should hear popping sounds as each jar seals. When completely cool, the middle of each lid should be sunken inward and should not spring back when touched.

Steps:

• In a large bowl, add the rhubarb and sugar; stir to coat evenly.
• Cover the bowl, and place it in the refrigerator overnight.
• The next morning, place the rhubarb mixture in a large kettle.
• Cook over medium heat, stirring constantly; until the mixture starts to boil, then lower the heat just a bit, and cook for 12 minutes (stirring constantly).
• Remove the kettle from the heat, add the gelatin powder, and keep stirring for 1 minute.
• Add the can of pie filling, and stir thoroughly until mixed through.
• Return the kettle to the stove. Start to cook over medium heat; stirring constantly, until the mixture comes to a boil.
• Remove the kettle from the heat, and carefully ladle the jam into the sterilized glass jars.
• Cover the jars with the lids, then cool the jam to room temperature, before storing the jam in the refrigerator or freezer.

Steps:

• Process grapes in batches in a food processor until pureed. Transfer to a large saucepan.

Steps:

• In a large heavy saucepan, combine blueberries, rhubarb, lemon rind and
• juice and water. Bring to a boil, stirring frequently, reduce heat and
• simmer, very gently, for 10 minutes.
• Stir in sugar; increase heat to high and boil vigorously until jam reaches setting point. (218 - 220 degrees F), 10 to 15 minutes, stirring
• frequently.
• Remove from heat, skim off foam and stir for 3 to 5 minutes to suspend
• fruit evenly throughout jam.
• Fill prepared jars leaving a 1/4" headspace. Process in a boiling water bath for 10 minutes. Adjust time according to your altitude.

Steps:

• Place rhubarb, strawberries, lemon juice, fruit pectin, and butter into a large kettle over medium heat. (Butter is optional but helps keep jam from getting too foamy). Stir the fruit mixture to help the juice start to form, and add sugar, about 1 cup at a time, stirring constantly until sugar is dissolved and the juice is starting to simmer. Turn up heat to medium-high, bring the mixture to a full rolling boil, and cook and stir for 1 minute. Skim off any foam that forms.
• Sterilize the jars and lids in boiling water for at least 5 minutes. With a jelly funnel and a soup ladle, pack the jam into the hot, sterilized jars, filling the jars to within 1/4 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 5 minutes.
• Remove the jars from the stockpot and place onto a cloth-covered or wood surface, several inches apart, until cool. To help the jam set, don't move or touch the jars until cooled. 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.
