Jam Ingredients
- 4 cups fresh blackberries, rinsed
- 2 cups granulated sugar
- 2 tablespoons lemon juice
- 1 tablespoon lemon zest (optional)
- 1 packet (1.75 oz) fruit pectin (optional, for thicker jam)
Instructions
- Prepare the Berries: In a large saucepan over medium heat, combine the blackberries and lemon juice. Gently mash the berries using a potato masher or the back of a spoon to release their natural juices.
- Add Sugar and Zest: Stir in the granulated sugar and lemon zest, then bring the mixture to a gentle boil, stirring frequently to dissolve the sugar and prevent burning.
- Add Pectin if Using: If you are using fruit pectin for a thicker consistency, add it according to the packet instructions, and continue boiling the mixture for 1–2 minutes, stirring constantly to fully incorporate.
- Simmer the Jam: Reduce the heat slightly and let the jam simmer for 10–15 minutes, stirring occasionally, until it thickens and reaches your desired consistency. Check the thickness by placing a spoonful on a cold plate; if it wrinkles when pushed, the jam is ready.
- Cool and Store: Remove the saucepan from heat and allow the jam to cool slightly. Then pour the hot jam into sterilized jars and seal them. Refrigerate for up to 3 weeks or process the jars in a water bath for longer-term storage.
Notes
- For a seedless jam, strain the mashed berries through a fine mesh sieve before cooking.
- This recipe can be doubled; however, cooking time may need to be extended slightly to achieve proper thickness.
- Use sterilized jars and proper canning techniques for safe long-term storage.
