Songpyeon (Korean pronunciation: [sʰoŋpʰjʌn]) is a traditional Korean food made of glutinous rice. It is a type of tteok, consisting of small rice cakes traditionally eaten during the Korean autumn harvest festival, Chuseok. They have become a popular symbol of traditional Korean culture. Songpyeon are half-moon-shaped rice cakes that contain different kinds of sweet or semi-sweet fillings, such as sesame seeds and honey, sweet red bean paste, and chestnut paste steamed over a layer of pine needles, which gives them the fragrant smell of fresh pine trees. They were made into various shapes with the participation of family members and were often exchanged between neighbors.
