Equipment

  • 1 large saucepan
  • 1 Wooden spoon
  • 1 Potato masher or fork
  • 1 Ladle
  • 1 funnel
  • 4 sterilized 8-ounce jars with lids

Ingredients
  

  • 4 cups blackberries fresh or frozen
  • 3 cups granulated sugar
  • 1 tablespoon lemon juice
  • 1/2 teaspoon butter optional

Instructions
 

  • Place the blackberries in a large saucepan and lightly mash them with a potato masher.
  • Add the sugar and lemon juice to the saucepan and stir to combine.
  • Turn the heat to medium and bring the mixture to a gentle boil, stirring continuously.
  • Skim off any foam that rises to the top using a spoon.
  • Add butter to reduce foaming, if desired.
  • Continue boiling while stirring for about 30 minutes, or until the mixture thickens.
  • Test the jam by dropping a small amount on a cold plate and checking if it sets.
  • Once the desired consistency is reached, remove from heat.
  • Use a ladle and funnel to pour the hot jam into sterilized jars, leaving a 1/4-inch headspace.
  • Wipe the rims of the jars clean and seal with lids.
  • Allow the jars to cool at room temperature for 12 hours to set.

Notes

For the best flavor, use ripe, in-season blackberries, and avoid overcooking the jam to prevent it from becoming too thick. Ensure jars and lids are properly sterilized to extend the shelf life of your jam. If you prefer a seedless jam, consider straining the blackberries through a fine-mesh sieve before cooking.
