Step‑by‑Step Instructions for Slow Cooker Plum Butter
Step 1: Prepare the Plums
Begin by washing and halving 8 cups of ripe plums, taking care to pit them as you go. This is essential for achieving a smooth texture in your Slow Cooker Plum Butter. Once halved and pitted, place the plums in a large bowl or directly into your slow cooker for convenience.
Step 2: Combine Ingredients
Transfer the pitted plums into your slow cooker and add 1.5 to 2 cups of organic sugar along with 1/3 cup of lemon juice. For an added depth of flavor, tie 5-7 reserved pits in a piece of cheesecloth or muslin and include them in the mix. Set your slow cooker to the low setting to start the magic.
Step 3: Cook the Mixture
Cook the plum mixture uncovered for 8 to 10 hours on the low setting. Stir the mix occasionally during cooking to allow for even heat distribution. You’ll know it’s done when the consistency has reduced by half and has transformed into a rich, velvety sauce with a deep burgundy hue.
Step 4: Remove Pits and Blend
Once cooked, carefully remove the cheesecloth bag containing the pits, discarding it. Use an immersion blender directly in the slow cooker or transfer the mixture in batches to a conventional blender. Blend until you achieve a smooth texture, ensuring that your Slow Cooker Plum Butter is free of any lumps.
Step 5: Jar the Butter for Canning
If you plan to preserve your Slow Cooker Plum Butter, sterilize your canning jars ahead of time. Ladle the warm plum butter into the jars, leaving about 1/4 inch of headspace at the top. Wipe the rims with a clean cloth, seal tightly with lids, and prepare for water bath processing.
Step 6: Process the Jars
In a water bath canner, place the filled jars and ensure they are covered with water. Bring to a rolling boil and process half-pints for 10 minutes or pints for 15 minutes. This step is crucial for making your canned plum butter shelf-stable, allowing you to enjoy this delightful spread long after making it.
Step 7: Cool and Store
After processing, carefully remove the jars and set them on a clean towel or cutting board to cool completely. Once cooled, check that the seals are intact; the lid should not pop back when pressed. Store your jars of Slow Cooker Plum Butter in a cool, dark place for up to a year, savoring every sweet moment.
