Jatjuk is a traditional porridge originating from South Korea. The porridge is usually made with a combination of ground pine nuts, ground white rice, salt, and water. Finely ground pine nuts and ground rice are cooked in water and slowly simmered until the consistency of the porridge becomes slightly thick.

This mild porridge is typically seasoned only with salt and garnished with whole or crushed pine nuts. Due to the fact that it's easily digestible, jatjuk is often served to the elderly and recovering patients.
