Push the pulp through and get as much of the thick juices as possible as this helps the marmalade to set ... You can test it by placing a spoon of the jam onto a cold saucer and see if it sets.

Equipment: You will need eight 300ml/10fl oz clean jam jars with lids ... Bring the marmalade to a rolling boil for 10-15 minutes. Skim off any orange scum that rises to the surface.
