How to Make Homemade Blackberry Jam

  1. Gently wash and sort 4 cups of fresh blackberries, removing any stems or leaves.
  2. In a large, heavy-bottomed pot, combine the blackberries and 1 pouch (1.75 oz) of liquid pectin. Stir gently to combine.
  3. Heat the blackberry mixture over high heat, stirring constantly until it reaches a full rolling boil. This should take about 1-2 minutes.
  4. Once boiling, stir in 3 1/2 cups of granulated sugar all at once.
  5. Continue to stir constantly, and bring the mixture back to a full rolling boil. A rolling boil means that the mixture boils hard enough that when you run a spoon across the surface, the bubbles do not disappear immediately.
  6. Maintain a rolling boil for exactly 1 minute, continuing to stir constantly.
  7. Remove the pot from the heat. Carefully skim off any foam from the surface using a spoon.
  8. Ladle the hot jam into clean, sterilized 8-ounce jars, leaving 1/4 inch headspace at the top.
  9. Wipe the jar rims clean with a damp cloth.
  10. Place canning lids and rings on the jars, finger tightening only.
  11. Process the filled jars in a boiling water bath canner for 10 minutes. Make sure the water level is at least 1 inch above the jars.
  12. Carefully remove the jars from the canner and let them cool completely, undisturbed, for 12-24 hours. You should hear a ‘pop’ as the jars seal. Check for a seal by pressing the center of the lid; if it doesn't flex, it's sealed!
