Description
Blackberry Jam is a sweet and tangy homemade preserve made with fresh blackberries, sugar, lemon juice, and pectin. It captures the fresh-picked flavor of summer berries in every jar.
Ingredients
Scale
- 6 cups fresh blackberries
- 4 1/2 cups granulated sugar
- 1/4 cup lemon juice (freshly squeezed)
- 6 tablespoons powdered pectin
Instructions
- Prepare the jars and canner by simmering 7 (8-ounce) jars in hot water. Wash lids and bands in hot, soapy water.
- Rinse blackberries gently, removing stems and leaves. Place berries in a large saucepan.
- Crush blackberries slightly to release juices, then stir in sugar and lemon juice. Bring to a rolling boil over medium-high heat, stirring constantly.
- Stir in powdered pectin quickly, mix well, and return to a rolling boil. Boil hard for 1 minute, stirring constantly.
- Test gelling by placing a spoonful on a chilled plate. If it sets, continue; if not, boil 1 more minute and retest.
- Fill hot jars with jam, leaving 1/4 inch headspace. Remove air bubbles and wipe rims clean.
- Seal jars with lids and bands until fingertip tight.
- Process jars in boiling-water canner for 10 minutes (adjust for altitude if needed). Turn off heat, let sit 5 minutes, then remove jars.
- Cool jars undisturbed for 12-24 hours. Check seals—lids should not flex when pressed.
- Remove bands, wipe jars, label, and store in a cool, dark place up to 18 months.
Notes
Use ripe, plump blackberries for the best flavor. Proper canning ensures safe long-term storage.
