Tteokguk is a traditional Korean soup, commonly eaten during Seollal (New Year). The main ingredients include garaetteok (long rice cakes), broth, beef or other meat, and egg garnish. Eating tteokguk symbolizes becoming one year older, and it is believed to bring health and good fortune for the new year. The rice cakes are boiled in the broth, creating a soft and chewy texture.
