Ingredients
- 4 cups fresh blackberries
- 2 cups granulated sugar
- 2 tablespoons fresh lemon juice
Instructions
- Wash the blackberries thoroughly under cold water, removing any stems or damaged berries. Drain well.
- Place the blackberries in a large saucepan and gently mash them with a potato masher, leaving a few small chunks.
- Stir in the sugar and fresh lemon juice until evenly combined.
- Cook over medium heat, bringing the mixture to a gentle boil. Stir frequently and cook for 20–30 minutes until thickened.
- Test the jam by placing a spoonful on a chilled plate. Wait 30 seconds and push it with your finger. If it wrinkles, it's ready. If not, cook a few more minutes and test again.
- Skim off any foam from the surface for a smoother, clearer jam.
- Let the jam cool slightly before pouring into clean, sterilized jars. Cool completely before sealing and refrigerating.
Notes
- Frozen blackberries work well—thaw and drain before using.
- The jam will continue to thicken as it cools.
- For a seedless jam, strain the cooked mixture before jarring.
- Store refrigerated for up to 3 weeks or freeze for up to 6 months.
- Always use clean, sterilized jars for the best shelf life.
