Recipe Information
Ingredients
- 4 cups fresh blackberries
- 2 cups granulated sugar
- 2 tablespoons lemon juice
Instructions
Wash the blackberries thoroughly under cold running water, then drain well.
Combine the blackberries and granulated sugar in a large, heavy-bottomed pot. Stir gently to coat the berries with sugar.
Add the lemon juice to the pot and stir again to combine.
Place the pot over medium-high heat and bring the mixture to a gentle boil, stirring frequently to prevent sticking or burning.
Lower the heat to medium and continue cooking. Use a potato masher or wooden spoon to break down the blackberries as they soften.
Simmer the mixture for about 20–30 minutes or until the jam thickens. To test for doneness, place a small dollop of jam onto a chilled plate. If it holds its shape and wrinkles slightly when pushed with your finger, it’s ready.
Remove the pot from the heat and let the jam cool slightly.
Carefully transfer the jam to sterilized jars, leaving about 1/4 inch of headspace. Seal with lids.
Allow the jars to cool to room temperature before refrigerating or processing them in a water bath for long-term storage.
Store in the refrigerator for immediate use or keep in a cool, dark place if properly canned. Enjoy within 3–6 months.
