Ingredients Equipment Method Notes

Ingredients
  

  • 2 1/2 quarts fresh wild blackberries or frozen, thawed
  • 4 1/2 cups granulated sugar
  • 3 3/4 cups blackberry juice from cooked and strained berries
  • 1 teaspoon butter helps reduce foam
  • 1/2 cup water only if needed while cooking berries
  • 1 box Sure-Jell or powdered pectin optional, for firmer set
  • 1 tablespoon lemon juice optional but helps set and flavor balance

Equipment

  • Large heavy-bottom pot
  • Fine mesh strainer or cheesecloth
  • Ladle and canning funnel
  • Mason jars with lids

Method
 

  1. Wash blackberries gently under cool water and remove any leaves or stems. The berries should look clean and dark purple before cooking.
  2. Add berries to a large pot with a small amount of water and cook over medium heat for about 15 minutes until soft and juicy. The mixture will become fragrant and syrupy.
  3. Strain cooked berries through a fine mesh strainer or cheesecloth to collect about 3 3/4 cups of smooth blackberry juice. Do not press too hard or the juice may turn cloudy.
  4. Pour juice into a clean pot and add sugar, butter, and lemon juice. Stir over medium heat until sugar fully dissolves and mixture looks glossy.
  5. Bring mixture to a rolling boil and cook for 1 minute while stirring constantly. The jelly will deepen in color and slightly thicken.
  6. Remove from heat and carefully ladle hot jelly into sterilized mason jars using a funnel. Leave a small headspace at the top.
  7. Wipe jar rims clean, seal with lids and rings, then let sit undisturbed for 24 hours until jars “pop” and fully set. The lid should be slightly concave when sealed.

Notes

Let jars rest untouched for a full 24 hours to ensure proper sealing.
For a clearer jelly, avoid pressing too hard when straining the juice.
If jelly doesn’t set, let it rest 48 hours before recooking or adjusting.
