Fish maw is dried swim bladders of large fishes. A quick lookup on Online described it as Virtually tasteless which I disagree. I’ve purchased a number of grades of fish maw from Kuantan and Kota Kinabalu (both famed for seafood produce) and discovered that higher excellent ones scent and tastes noticeably greater. https://augustp3940.blogsvila.com/34558299/getting-my-花膠-to-work
