Good to Know
Beef broth and radish kimchi water Ratio: The perfect ratio is beef broth: radish kimchi water=2:1.
However, radish kimchi water is not necessary. If you don’t have any radish kimchi water, simply increase the amount of the beef broth.

Optional Ingredients and Substitutions
Beef bones: If you don’t have the beef bones, increase the amount of beef. However, without beef bone the soup will not have the same depth.
Radish kimchi water: If you don’t have time to make it, just increase the about of beef broth. Or if you happened to have radish water kimchi (dongchimi), simply use the juice from the kimchi.
Pickled Radish: If you don’t have time to make it, you can simply omit. However, it will not be as tasteful as the ones you get from restaurants.
Beef broth: You can use the anchovy broth or chicken broth instead of beef broth.
