Mochi is made of steamed and mashed sticky rice with elastic and tender but chewy texture. Such texture has become a special feature which was widely used in bakery and confectionery. For example, mochi will be added to traditional Chinese pastry to enrich the texture. Nowadays, as cookie and biscuit are consumed more and more, a mix of western confectioneries and eastern sweets was developed. As a variant of wagashi, eastern mochi cookie is a cookie with soft and tender crust and mochi filling. As for western mochi cookie, chocolate chip cookie is commonly seen.
