I just had my stink bean dish just now. Stink beans is hard to prepare, if you do not clean the stink beans properly, you would extra flavour the dish. It is actually a worm that live in stink beans, just like a dried shrimp or dried prawn when cooked. So it is funny is someone tell it has dried shrimp when you say you did not place any.
It depends on how the beans are cutted, if you saw cooked stink beans which cut in half in whole beans, the beans unopened during preparation, don't it eat, you will eat the "dried prawn" or "dried shrimp". I remembered it so well because I seen many shapes of cutted stink beans, I wondered if the creative cutting remove the worm.
