Fish maw is dried swim bladders of enormous fishes. A fast lookup on Internet described it as almost tasteless which I disagree. I’ve purchased a few grades of fish maw from Kuantan and Kota Kinabalu (the two famed for seafood develop) and observed that increased quality types odor and preferences drastically improved. https://mylesz9528.liberty-blog.com/34560621/花膠-an-overview
