Ingredients

  • 1 pound fresh blueberries
  • 2 tablespoons Lemon Juice (fresh)
  • 3 tablespoons Ball Classic Pectin
  • 3 ⅓ Cups Sugar

Instructions
 

  • Rinse and drain the blueberries (fresh or frozen) and crush them using the potato masher method or my rolling pin and zip top bag method.
    1 pound fresh blueberries
  • Measure out 2 ⅔ cup of crushed berries into a 6 quart stainless-steel or enamel Dutch oven.
  • Stir in the lemon juice and the pectin.
    2 tablespoons Lemon Juice, 3 tablespoons Ball Classic Pectin
  • Over high heat, while stirring,  bring the mixture to a full rolling boil that can not be calmed down when stirred.
  • Add the sugar and stir to dissolve the sugar. Return to a full rolling boil Boil hard 1 minute, stirring constantly.
    3 ⅓ Cups Sugar
  • Remove from heat and skin the foam, if necessary.
  • Ladle the jam in to a hot jar, leaving ¼ inch head space. Wipe the rim of the jar with a damp paper towel, removing any drips of jam. 
  • Center the lid on the jar. Apply the band and adjust to fingertip-tight. Using the jar lifter, place the jar in the boiling water canner. 
  • Repeat until the jars are filled. Be sure to complete a filling a jar from ladle to lifting before starting the next jar. 
  • Process the jar 10 minutes, adjusting time for altitude.
  • Remove the jars from the water bath canner and place on clean towels to cool completely.

Notes

  • After 24 hours, test lids for seal, remove rings and store in a cool dry place.
  • Be sure to store any jars with lids that did not seal in the refrigerator.

For Lower Sugar Recipe

  • Add ⅔ cup of water or unsweetened fruit juice, just as apple or pear, to the blueberries and lemon juice. 
  • Substitute 3 Tablespoons of Ball Low or No-Sugar Needed Pectin in for the Classic pectin.
  • Reduce the sugar to 1 cup.
  • The jam will be looser in consistency and set than the classic recipe but will still be delicious!
