Ingredients
Scale
- 4 pounds ripe plums, washed and pitted
- 4 cups water
- 6 cups granulated sugar
- 1/4 cup lemon juice
- 1 package (1.75 ounces) powdered pectin
- 1 tablespoon butter (optional, to reduce foaming)
- 6 half-pint canning jars with lids and bands, sterilized
Instructions
- Step 1: Combine plums and water in a large saucepan or stockpot. Bring to a boil over medium-high heat. Reduce heat and simmer for 20-25 minutes, or until plums are soft.
- Step 2: Place a jelly bag or several layers of cheesecloth over a large bowl. Pour the cooked plum mixture into the bag and let the juice drip through undisturbed for several hours or overnight. Do not squeeze the bag, as this will result in cloudy jelly.
- Step 3: Measure 4 cups of plum juice into a large, clean saucepan. Add the lemon juice and butter (if using). Stir in the powdered pectin.
- Step 4: Bring the mixture to a rolling boil over high heat, stirring constantly. Add the sugar all at once and continue stirring constantly until the sugar is completely dissolved.
- Step 5: Continue to boil hard for 1 minute, stirring constantly. Remove from heat and skim off any foam.
- Step 6: Ladle the hot jelly into the sterilized jars, leaving 1/4-inch headspace. Wipe the jar rims clean. Place lids on jars and screw on bands until fingertip tight.
- Step 7: Process in a boiling water bath for 10 minutes (adjust time for altitude). Remove jars from the water bath and let them cool completely on a towel-lined surface. Check for proper sealing by pressing down on the center of each lid; it should not flex.
Notes
- Store sealed jars of plum jelly in a cool, dark pantry for up to a year; refrigerate after opening.
- For a quick, delightful treat, warm a spoonful of plum jelly and drizzle it over vanilla ice cream or yogurt.
- Try pairing your homemade plum jelly with sharp cheeses on a charcuterie board for a sweet and savory combination.
- Don't rush the juice dripping process; letting it strain undisturbed overnight ensures a beautifully clear jelly.
