Anyone familiar with a particular edible kelp "o'go" or a shellfish, "o'pihi" that can be found off the shores of Hawaii?
I thought kelp was kelp whenever eaten, but according to a co-worker, he says that he used to gather this particular species and either eat it fresh (washed with ocean water) or dry it to be eaten.
This co-worker also told about the "o'pihi", which sounds like a chiton, that can be cut off the rocks, rinsed in ocean water and deftly popped into the mouth. Incidentally this guy said that the last time he did this, his new wife was horrified and kids around them ran back to their mothers to tell the news.
I am planning a trip to Kauai and I was interested in trying these things and well, first wanted to find if this is permitted and second, was hoping someone could offer some pointers.
