Bo Torrey (how is Bo these days?) once told me in his inimitable way that pipi meat is delicious but annoyingly crunchy?his predominant memory from a pearl-spitting oyster feed on a beach in Manihiki in the 90s. Actually pipi are considered a plague by the cultured pearl industry, much as barnacles to tall ships.In some out of the way places, the sand is awash in these little golden pearls. But don't try picking them up if you are just visiting - the locals "harvest" them. No one nucleates these oysters commercially, as far as I know. The shells are tiny.
