Make It

Tap or click steps to mark as complete

  • Bring boiling-water canner, half full with water, to simmer. Wash jars and screw bands in hot soapy water; rinse with warm water. Pour boiling water over flat lids in saucepan off the heat. Let stand in hot water until ready to use. Drain well before filling.
  • Crush blackberries thoroughly, one layer at a time. (Press half of the pulp through a sieve to remove some of the seeds, if desired.) Measure exactly 4 cups prepared fruit into 6- or 8-qt. saucepot.
  • Add sugar; stir. Add butter to reduce foaming. Bring mixture to full rolling boil (a boil that doesn't stop bubbling when stirred) on high heat, stirring constantly. Stir in pectin. Return to full rolling boil and boil exactly 1 min., stirring constantly. Remove from heat. Skim off any foam with metal spoon.
  • Ladle immediately into prepared jars, filling to within 1/4 inch of tops. Wipe jar rims and threads. Cover with two-piece lids. Screw bands tightly. Place jars on elevated rack in canner. Lower rack into canner. (Water must cover jars by 1 to 2 inches. Add boiling water, if necessary.) Cover; bring water to gentle boil. Process 10 min. Remove jars and place upright on towel to cool completely. After jars cool, check seals by pressing middle of lid with finger. (If lid springs back, lid is not sealed and refrigeration is necessary.)

We have a lot of wild blackberries here, and because of this, blackberry jam has been a family favorite since I was very young. This is the only recipe I have found that is nearly identical to the one my grandmother used.

I substituted Ollaliberries for the blackberries - 1 cup Oalliberry juice and 3c mashed berries (to reduce the seed count a bit). I also added 1 tbsp lemon juice. It is great!
