Pan-fried shark's fin pancake? I've never heard of such a thing. I can't even imagine such a thing.
(Dried) Shark's fin has a very similar texture to vermicelli. Imagine if you pan-fried vermicelli in a pancake form until it was crispy. Now, imagine if that vermicelli, prior to pan frying was infused with the flavors of a very savory broth, and that's part the idea.
