Haishen is a delicacy. I sometimes buy them at the grocery store when I passed by them, out of no apparent reason nor did I have a plan as how and when to cook them. IF the slugs survived that long, I might throw them into the soup. Eat-first-asking-question-later would not apply here: they would disappear in the hours long cooking journey. Most time I’d throw them away.
I don’t know how to cook sea cucumbers.
Passing by this store on Grand Street in Chinatown the other day. Wow, they sell many kinds of slugs:
