Miso soup is a Japanese national dish of miso broth, wakame seaweed, tofu and nameko mushrooms. Miso broth is made by fermentation of soybeans, rice, barley and wheat, which makes it have a bright, memorable taste, so beloved by fans of Japanese cuisine. We have saturated the classic recipe with the delicate salty taste of fresh mussels, which makes this dish a worthy start for a dinner inspired by Japan. We added seafood to this soup for the fullness of taste.
