But jam comes in jars of a minimum size and sometimes it goes mouldy before finishing.

  1. Keep it in the fridge
  2. Only use clean spoons (don't let breadcrumbs, butter, saliva touch the jam in the jar)
  3. Immediately close the jar after taking something out.

-> rarely ever any mold. I keep my jams fresh for months this way.
