Ingredients
Scale
Ingredients:
- 4 cups fresh blackberries (rinsed and drained)
- 2 cups granulated sugar
- 1 tablespoon lemon juice
- 1/2 teaspoon lemon zest (optional)
- 1/2 teaspoon butter (to reduce foaming, optional)
Instructions
- Prepare the Jam: In a large saucepan or deep skillet, combine the blackberries, sugar, lemon juice, and lemon zest (if using). Gently mash the berries to release their juices. Bring to a boil over medium-high heat, stirring frequently. Add butter to reduce foam.
- Cook the Jam: Boil the mixture for 15–20 minutes or until it thickens and reaches 220°F (104°C). Alternatively, test by dropping a spoonful on a chilled plate—it should hold its shape when you run your finger through it.
- Cool and Store: Remove from heat, let cool slightly, then pour into clean jars. Cool completely before sealing. Refrigerate for up to 3 weeks or freeze for 3 months.
Notes
- For seedless jam, strain mashed berries through a fine mesh sieve before cooking.
- Adjust sugar to taste based on berry sweetness.
