I really recommend watching "Discover China: A Tale of Tofu." You will be shocked and amazed. Did they really just make those pure white blocks of bean curd in a traditional dirt-floor house in China? Did they just say "plaster of Paris"? Was plain tofu really not enough? How have I never ever heard of all the crazy variations of tofu - black tofu, fuzzy tofu, blood tofu??
For serious, rent it.
