Chop chilies finely.
Add all other ingredients. Bring to a boil and reduce heat to a simmer. Continue cooking for a further 15 minutes, or until plums become soft. This makes an excellent chutney for roast pork, other meats, and for sandwiches. For an interesting basing sauce for ribs, transfer sauce to a food processor and blend to a paste.
