Senbei (煎餅, alternatively spelled sembei) are a type of Japanese rice cracker. They come in various shapes, sizes, and flavors, usually savory but sometimes sweet. Senbei are often eaten with green tea as a casual snack and offered to visiting house guests as a courtesy refreshment.
Senbei are usually cooked by being baked or grilled, traditionally over charcoal. While being prepared they may be brushed with a flavoring sauce, often one made of soy sauce and mirin. They may then be wrapped with a layer of nori. Alternatively they may be flavored with salt or "salad" flavoring, among others.
In China, the same characters used to write senbei are read jiānbǐng (煎饼; 煎餅; jiānbǐng); the term refers to a totally different food which is a crepe and is more similar in preparation to okonomiyaki among Japanese foods. In Japan, senbei are hard and crispy, and are bite-sized snacks rather than street-food meals. However, crackers similar to Japanese senbei can be found in China today and their modern Chinese name is 仙贝; 仙貝; xiānbèi, which reflects the Japanese-language pronunciation of "senbei" (煎餅).
Sweet senbei (甘味煎餅) came to Japan during the Tang dynasty, with the first recorded usage in 737 AD, and still are very similar to Tang traditional styles, originally often baked in the Kansai area, of which include the traditional "roof tile" senbei. These include ingredients like potato and wheat flour or glutinous rice, and are similar to castella cakes, distinctly different from what most people would consider as senbei today, though traditional senbei such as this can still be found, e.g. Iga meibutsu katayaki, in Iga City.
There are several types of traditional Japanese senbei. They can be baked or deep-fried and sometimes sweetened. Aside from rice, wheat flour or starch can be used. Some varieties even use foods other than grains, such as sakana senbei (fish-senbei), renkon senbei (lotus root senbei) and hone senbei (bone-senbei).
Kansai senbei tend to use glutinous rice and are lightly seasoned and delicate in texture (saku saku). Kantō senbei were originally based on uruchimai, a non-glutinous rice, and they tend to be more crunchy (kari kari) and richly flavored.
Thin Japanese rice crackers (薄焼きせんべい usuyaki senbei) are popular in Australia and other countries.
