You know, I've written about these. Mused on the name for hours of personal entertainment. It means 4-sided noisy fruit. Dreamed about all the things I'd do with them if I went to Thailand. But until recently I had never set eyes on one. Until they show up in the farmers market. The farmer told me his dad brought the seeds and has been trying to grow them for years and finally they bore enough to sell. Some were stir fried the others are being pickled. Where else could this happen but in Stockfish CA? P.S. They are beans.
