Ingredients

Scale
  • 46 cups fresh blackberries
  • 46 cups sugar

Instructions

  1. Sterilize jars and lids by washing them in very hot water or running them through the dishwasher. Boil lids in a saucepan to keep them clean.
  2. Rinse the blackberries in a colander and mash them until there are no big seeds left.
  3. Measure out an equal amount of sugar to match the mashed berries.
  4. In a large saucepan, cook the mashed berries over high heat, stirring constantly until they boil. Let boil for 3 minutes.
  5. Gradually stir in the sugar and return the mixture to a boil. Keep it boiling for another 3 minutes.
  6. Remove from heat and whisk for 3 minutes to help thicken the jam by activating the natural pectin.
  7. Carefully pour the jam into sterilized jars, filling them to the narrow part of each jar.
  8. Seal each jar with a hot lid and tightly screw on the ring. You’ll have about 8 jars of jam!

Notes

This jam stores well for months in a cool, dark place. For longer shelf life, consider using a water bath canning method after sealing the jars.
