Songpyeon is a traditional Korean food made of rice powder and is a type of tteok, small rice cakes, with a variety of fillings used. Its shape resembles a half-moon and it is a representative rice cake of Korean holidays and traditional culture. Songpyeon is typically eaten during the Korean autumn harvest festival, Chuseok, where it is often prepared by families at home. The rice cakes are half-moon shaped and typically contain sweet or semi-sweet fillings, such as soybeans, cowpeas, chestnuts, jujubes, dates, red beans, sesame seeds, or honey. They are steamed over a layer of pine needles, which gives them a distinctive taste and the fragrant smell of fresh pine trees. The colors typically include white, green, red, and yellow. Songpyeon is used to show gratitude for the years harvest by placing it on a charye, an ancestral memorial ritual, and offering it to ancestors. It is also given to other family members and close neighbors as a sign of respect and efforts to avoid bad luck within the family.
