Place the pumpkin in a large pan, with the water, oranges, lemons and ginger. Bring to a boil and then simmer for 45 minutes – 1 hour until the citrus peel is very soft.
Add the sugar, stirring until it has dissolved. Return to a boil and then cook over medium heat until the mixture is thick enough for a wooden spoon to be drawn through the center to leave a clear channel.
Pour the marmalade into cool, sterilized jars and seal with waxed discs or twist top lids. Label and store.
