Filipino food combines Eastern and Western ideas and is strongly influenced by Chinese, Spanish and American traditions. Filipino food is sometimes identified by the way it fuses Asian and European ingredients. For example, in the robust and popular Pork Menudo dish, some recipes have it blending tomato sauce with soy sauce, while others have it combining cheese and bay leaf with soy sauce. Local Southeast Asian ingredients like chilies, coconuts, shrimp paste, lemongrass, and fish sauce or patis are present in Filipino cooking. Chinese traders brought with them not only their silks and ceramics but also Chinese cooking traditions like stir-frying and steaming. The Filipino pancit has its roots in noodle soup dishes from China, the lumpia finds its origins in Chinese spring rolls, while the siaopao and siaomai are similar to the popular Chinese dim sum dishes of steamed buns and dumplings.
