Equipment

  • Large saucepan
  • Wooden spoon
  • Potato masher
  • Fine Mesh Strainer (optional)
  • Candy Thermometer (optional)
  • Glass Jar with Lid

Ingredients
  

  • 4 cups fresh blackberries
  • 2 cups granulated sugar
  • 2 tablespoons fresh lemon juice
  • ¼ teaspoon salt

Instructions
 

  • Combine the blackberries and sugar in a large saucepan. Let the mixture sit for 20–30 minutes until the berries begin to release their juices.
  • Place the saucepan over medium heat and bring the mixture to a gentle boil, stirring occasionally. Mash the berries as they soften.
  • Continue cooking, stirring frequently, until the berries break down and the mixture starts to thicken.
  • Stir in the lemon juice and salt, then simmer for a few more minutes until the jam reaches your desired consistency.
  • Remove the jam from the heat and, if desired, strain it through a fine-mesh sieve to remove the seeds.
  • Let the jam cool slightly, then transfer it to clean jars. Cool completely before sealing and storing in the refrigerator.
