Korean traditional food is made of various materials, ranging from vegetables to meat.  Hence, you can find many dishes that are not spicy or hot in taste. Also, the primary seasoning used for cooking is soybean paste.  Korean traditional food does not use fish sauce but instead uses soy sauce or soybean paste as its main seasoning. Also, salted seafood is used for flavor enhancement. However, some dishes use fish sauce imported from Japan. Thus, you should avoid confusing the two seasonings when you first visit Korea.
