Ingredients
  

  • What You'll Need
  • Here's everything you'll need to pull this off:
  • 4 cups fresh blackberries about 2 pounds, or use frozen
  • 1 ½ cups granulated sugar
  • 2 tablespoons lemon juice fresh, not bottled
  • 1 packet 1.75 oz fruit pectin
  • That's it. Four ingredients and you're already ahead of 90% of the jars on grocery store shelves.

Equipment

  • Tools You'll Need
  • A large, heavy-bottomed pot (this matters more than you'd think)
  • A potato masher or fork
  • A fine mesh strainer (optional, for seedless jam)
  • A candy thermometer (helpful, not required)
  • Wooden spoon
  • Mason jars with lids (4-5 half-pint jars)
  • Ladle and a canning funnel (makes life way easier)
