What You'll Need

  • 6 cups blueberries (washed and picked over)
  • 2 tablespoons lemon juice
  • 4 cups sugar
  • 1 pouch (3 ounces) liquid fruit pectin

How to Make It

  1. Prepare the water bath canner and jars. Add water to a canner with a rack; add cleaned jars and bring to a boil. Reduce heat to keep jars hot. The water should be high enough to be at least 1 inch above filled jars. I usually fill it about halfway and I keep a kettle or saucepan of water boiling on another burner to add to the canner as needed.
  2. Heat water in a small saucepan; put the lids in the saucepan and bring almost to the boil; lower heat to very low to keep the lids hot.
  1. Scald jars in boiling water and keep warm.
  2. Pour about 3/4 of the berries into a large pot and mash.
  3. Stir in the remaining berries, sugar, and lemon juice. Stirring constantly, bring to a rolling boil which cannot be stirred down. Immediately add the pouch of fruit pectin. Stirring constantly, bring back to the boil and continue boiling for 1 minute. Skim off excess foam, if necessary, and ladle the hot berry mixture into prepared jars.
  4. With a clean dampened cloth, wipe the rims of the jars. Place the flat lids on the jars then close caps with screw-on rings firmly. Arrange the filled jars in the canner and add more water, as needed, to be at least 1 inch above the jars. Bring to a full boil. Cover and continue boiling for 10 minutes. Remove the preserves to a rack to cool completely.
  5. Check for seals (the middle of the caps should have made a popping sound while cooling and will stay down.
