餅 (mochi) is a traditional Japanese rice cake made from glutinous rice. The rice is steamed and then pounded until it becomes a smooth, sticky dough. Mochi can be enjoyed in various forms, such as plain, filled with sweet or savory ingredients, or used in desserts like daifuku and mochi ice cream. Mochi is often associated with Japanese festivals and celebrations, particularly during the New Year when it is used to make a special soup called ozoni. It is also popular in other Asian cultures, where similar rice cakes are made, showcasing its versatility and cultural significance.
