  3. Bring to a boil over medium heat, stirring regularly to prevent the mixture from sticking.

4. Potting and storage

  1. Sterilize the jars by immersing them in boiling water for 10 minutes, then drain them.
  2. Ladle the hot jam into the jars, leaving a small space at the top.
  3. Close the jars immediately with the lids and turn the jars upside down to create a vacuum.
  4. Allow to cool completely before storing in a cool, dry place.
