This recipe is very similar to the previously posted beef honeycomb tripe recipe: Doubanjiang Beef Tripe with Bell Peppers (辣豆瓣酱青椒牛柏葉, Laat6 Dau6 Faan6 Zoeng3 Ceng1 Ziu1 Ngau4 Paak3 Jip6). This recipe uses beef book tripe instead, Shiitake mushrooms, and bell peppers cut into strips to match shape of the tripe pieces. Beef book tripe is another of the cow’s stomachs that are readily available at your local Asian market. While the honeycomb tripe has a honeycomb pattern on one side, the book tripe resembles a book with open pages. The book tripe is commonly served as a Chinese Dim Sum dish and has a crunchier texture than the honeycomb.
