Instructions

  1. Put the lemon juice into a cup measure, then make up to a full cup with water.
  2. Put all ingredients into a saucepan and boil (don't just simmer) for 10 minutes, stirring constantly after it boils - must not stir until it has boiled or it will go candied.
  3. As Chef Dudo mentioned in her review, it thickens on cooling.
