Equipment

  • Water Bath Canner
  • half pint canning jars, lids, rings

Ingredients

  • 18 oz blackberries (3 clamshells)
  • 2 apples peeled and sliced
  • 1/2 C water
  • 1/4 C lemon juice
  • 4.5 C granulated sugar
  • 1 pkg Sure Jell low sugar pectin

Instructions

  • Combine blackberries and sliced apples and puree in blender. Transfer to a large stockpot. Add water, lemon juice and pectin.
  • Heat to a boil, stirring constantly.
  • Stir in the sugar, and return the mixture to a full rolling boil that reaches a temp of 220 degrees F. Boil hard for 2 minutes, stirring constantly. Remove from heat. Skim off any foam with a metal spoon.
  • Immediately ladle jam into hot, sterilized, half pint canning jars. Allow 1/4 inch headspace per jar. Wipe jar rims and adjust lids. Process in a hot water bath for 10 minutes (start timing when water starts to boil). 
  • Remove jars from canner; cool on counter or wire rack. As jars cool, they will seal (you will hear them "ping"). Jars may take up to 24 hours to seal - once sealed, lids will not bounce back when pushed down.
