  • Ladle hot blackberry jam into the jar leaving about a 1/4" headspace. Use a funnel if that helps with the size jar you are canning.
  • Using a damp cloth, wipe off each jar lid clean, add lid and ring to finger tightness. Lift with jar lifter and add back to hot water canner.
  • When all jars are added to the water bath canner, make sure that the water covers them all by about an inch.
  • Cover canner with a lid and begin processing time when water begins to boil in canner.
    NOTE: Processing time is determined by the size jars. Half pints process in 10 minutes; pints-15 minutes.
  • When processing time has ended, remove lid and turn off heat.
    Using jar lifter, add jars to a dishcloth covered surface out of drafts for 12-24 hours before moving.
  • Check to make sure each lid has indented and sealed before labeling and adding to pantry.
