Mochi (餅) is a Japanese rice cake made of
mochigome, a short-grain japonica glutinous rice, and sometimes
other ingredients such as water, sugar, and cornstarch.
The rice is
pounded into paste and molded into the desired shape. In Japan, it is
traditionally made in a ceremony called mochitsuki. While eaten
year-round, mochi is a traditional food for the
Japanese New Year, and is commonly sold and eaten during that time.
