Blueberry Jam Without Pectin
Blueberry Jam Without Pectin uses fresh or frozen blueberries cooked down with sugar and lemon juice to develop a thickened jam. The recipe simmers the fruit mixture until it reaches a set temperature, encouraging natural pectin release and gel formation. The jam offers a sweet, fruity spread with the unmistakable blueberry character, suitable for canning or refrigeration.

Ingredients
- 6 cups blueberries approximately 2 lbs
- 1 1/ 4 - 1 1/2 cups sugar
- 1 tablespoon lemon juice
Instructions
- Jam: Add berries, lemon juice, and sugar to a large pot on medium. Use a masher to gently mash and break up the berries, releasing some of the juice. Stir so that the sugar dissolves in the juice. Turn the heat up slightly and bring to a boil. Reduce heat to medium-low to maintain a gentle simmer and let simmer, reduce, and thicken. The jam will be ready when the internal temperature of the jam reaches 221 degrees F.
- Canning: While the jam simmers, sterilize your jars and lids if canning and set aside. Once the jam is done, fill jars, being sure to leave 1/4 inch headspace, and add lids and secure tightly. Water bath to store. Always be sure to follow safe canning guidelines.

Notes
- Use a large pot as the berries foam and can overflow during simmering.
- Store jam in the refrigerator for up to 3-4 weeks or freeze for up to 3 months.
- For longer storage, follow safe canning practices using sterilized jars and water bath processing.
- Frozen blueberries can replace fresh by macerating them in lemon juice before cooking.
- Sugar amounts can be adjusted; more sugar or alternative sweeteners can be used to modify sweetness.
- Doubling the recipe increases cooking time accordingly.
