Best Strawberry Rhubarb Slow Cooker Jam Recipes

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.

STRAWBERRY-RHUBARB JAM

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.

RHUBARB STRAWBERRY JAM - SLOWCOOKER RECIPE

Steps:

• Add the quartered strawberries and chunks of rhubarb to your slow cooker. Cover with the sugar and cinnamon, add the lemon juice and give everything a good stir. (If you have time, leave the fruit to macerate in the fridge overnight, covered with the lid or plastic wrap. Doing this will release some of the natural pectin present in the fruit, helping the jam to set. If you don't have time, don't worry about it, you'll still get a good batch of jam!). Turn the slow cooker on low and set the timer for 7 hours. Cover with lid. After 5 hours, remove the lid so the juices can evaporate and thicken in. 1 hour later (after 6 hours total cooking time), mash the fruit using either a potato masher or a hand blender. The potato masher will give you a chunkier texture. Let the jam cook on low for another hour or until the excess of juices has evaporated. Ladle your fresh batch of homemade jam in a jar and let it cool down on the counter before refrigerating. The jam will keep for 2-3 weeks in the fridge or 6-12 months in the freezer - just make sure to use a freezer safe container if you're going that route.
