Ox (beef) bone soup, Seolleongtang

Seolleongtang (ox bone soup) is one of the most popular soups served in restaurants in Korea. The soup is renowned for its milky white color, remarkably thick taste and its richness in protein and calcium. It's eaten for breakfast, lunch and dinner throughout the year. It’s especially popular at home during the winter. Korean mothers prepare the soup for 몸보신 (mom bo shin); the soup helps to enhance health and stamina for the family.

Seolleongtang is time consuming to make; the ox bones are simmered over a low flame over a period of several hours to an entire day, to allow the flavor to be gradually extracted from the bones. Therefore, large batches are often prepared at once and the extra broth is frozen to be used later as a base for other dishes like ddeokguk (rice cake soup), manduguk (dumpling soup) and siraegiguk (radish stem soup).

Seolleongtang has long been a part of Korean cuisine. One possible origin of the soup can be traced to the Joseon era during the king's ancestry ritual. During the ceremony a cow would be killed in sacrificial offering, and afterwards this cow would be made into a soup. Another possible origin is from a Mongolian method of cooking beef in water.

The soup is served without any seasoning. The seasoning is done at the table: chopped green onions, minced garlic, salt and pepper are served on the side, added before eating to personal taste. Rice and kkakdugi (cubed radish kimchi) are always served with the soup. Dadaegi 다대기 (spicy seasoning) is sometimes served on the side.

Some people like to add whole garlic, ginger, green onions or radish while boiling the bones. I personally don’t like adding herbs and seasonings during the boiling process because I prefer the pure flavor of the ox bone in the soup.

Special Tools and Equipments:

-large bowl
-fine strainer
-Korean Stone Bowl

tips:

Good to know
Where to find ox bones
Most Asian markets or Korean grocery stores should have ox bones. You can use leg bones, tail bones, head bones or a mix of the three types of bones.

How pick good ox bones
Ox bones should be white and shiny on the surface (not yellowish) and the middle of the cross section should be pinkish (not blackish).

The broth from boiling the meat
You can save and freeze the beef broth and use it to make other Korean dishes such as buckwheat noodles in chilled broth (naengmyeon).

Optional Ingredients and Substitutions
Beef: Instead of beef flank, you can use beef shank.
Herbs and seasonings: Some people like to add whole garlic, ginger, green onions or radish while boiling the bones. I personally don’t like adding vegetables and seasonings during the boiling process because I prefer the pure flavor of the ox bones in the soup.
