  2. Cover with strong cap paper.

  3. Brush the cap paper with egg white to seal.

  4. Label each pot with its contents and date.

What each ingredient does

Fresh fruit
Provides the main flavour and bulk of the preserve.
Sugar
Adds sweetness and helps preserve the fruit.
Egg white
Acts as a glue that helps the cap paper stick and seal the pot.

The step that matters

Do not boil the fruit too long. Prolonged boiling can harden the fruit and spoil its texture, so the fruit should be cooked only until it is done.
