Put all the ingredients, except the sugar, into a large pan and stir well. Bring slowly to the boil, then reduce the heat, cover and simmer for 10 mins, until the plums are tender.

Pot into sterilised jars (see Know-how, below), seal, label and store for at least 2 weeks before eating. Will keep for up to 6 months in a cool dark place.
