Add the sliced kimchi, kimchi juice, gochugaru, and the soup soy sauce (or saeujeot, salted shrimp) to the anchovy broth. Bring it to a boil. Cook over medium high heat until the kimchi turns translucent.
Add the bean sprouts and garlic. Cook, covered, for 3 - 4 minutes. Do not open the lid while the bean sprouts are being cooked, or the raw bean smell will linger even after cooked. Once the bean sprouts are cooked, adjust the seasoning.
