Ingredients
Scale
- 3 pounds fresh plums, pitted and chopped
- 3 cups granulated sugar
- 1/4 cup lemon juice
- 1/4 cup water
Instructions
- In a large, heavy-bottomed pot, combine the chopped plums, sugar, lemon juice, and water.
- Stir well to combine, then let the mixture sit for about 30 minutes to allow the plums to release some of their juices.
- Place the pot over medium heat and bring the mixture to a gentle boil, stirring frequently to prevent sticking.
- Once boiling, reduce the heat to low and simmer for about 30-40 minutes, or until the jam has thickened and reaches a temperature of 220°F (104°C) on a candy thermometer. Stir frequently to prevent burning.
- To test if the jam is ready, place a small plate in the freezer for a few minutes. Drop a small spoonful of jam onto the cold plate. Let it cool for a minute, then push the jam with your finger. If it wrinkles and doesn’t run, it’s ready.
- Remove the pot from the heat and let the jam cool for a few minutes. Skim off any foam that rises to the surface.
- Ladle the hot jam into sterilized jars, leaving about 1/4 inch of headspace.
- Wipe the rims of the jars clean, place the lids and rings on, and tighten the rings.
- Process the jars in a boiling water bath for 10 minutes (adjust time for altitude).
- Remove the jars from the water bath and let them cool completely on a towel-lined surface. You should hear the lids pop as they seal.
- Store sealed jars in a cool, dark place for up to a year. Once opened, store in the refrigerator.
Notes
- For a smoother jam, you can use an immersion blender to puree the plums after they have softened.
- Adjust the sugar to your preference. Some people prefer less sugar, which will result in a more tart jam.
- You can add a touch of cinnamon or other spices to the jam while it’s simmering for added flavor.
- Always use clean, sterilized jars and lids for safe canning.
