  1. Wash the blackberries and juice the lemon.
  2. In a jam pan, mix together the blackberries, sugar and lemon juice.
  3. Put the pan on the hob to begin cooking the preserves.
  4. Bring to the boil. Once it reaches boiling point, if using jam sugar, count 7 minutes. If not, count 15 to 20 minutes.
  5. 2 minutes before it is done, crush the blackberries with a slotted spoon.
  6. It’s ready! Check its progress by pouring a few drops onto a cold plate and tilting it. The preserve should very slowly trickle down.
  7. Immediately pour the jam into the Le Parfait jam jars. Seal the jars and upturn them for 1 min, then turn them back again and leave them to cool.
