Korean mushroom soup (Beoseot-deulkkae-tang: 버섯들깨탕) is a delicious, nutritious, savory soup made with mushrooms and perilla seeds powder. The perilla seeds powder makes the broth soft and nutty, and the beef brisket and the mushrooms are chewy, soft, and crispy, giving this soup a very unique taste and texture.
