Microwave Three Fruit Marmalade

Homemade preserves are always the best and using the microwave is a quick and easy way to produce small quantities.

  1. Peel the fruit, avoiding the pith and shred the peel thinly.

  6. Sterilise the jam jars and lids.

  8. Strain the muslin bag into the fruit, pressing well to extract maximum pectin.
  9. Cook the fruit again for 12 minutes.
