Spare-Ribs with Salted Chinese Plums

Salted or pickled plums were a treat I used to get as a child, instead of chocolate, so I was fascinated to see in Hong Kong entire stores filed with dozens of varieties of salted plums for eating and cooking. Innovative methods to use them to flavour foods have been created, as in this spare-ribs dish. The plums should be removed before serving, because even after cooking they have a strong flavour. I love them, but they are an acquired taste.
