Miso soup is a traditional soy-based soup made from a stock called dashi, miso paste, and various additional ingredients such as seaweed or tofu. It is estimated that more than 70% of Japeanese people consume the soup for breakfast, although it is commonly available at any time of the day.
In Japanese restaurants in the United States, miso soup is often offered as an appetizer. The soup is thought to have medicinal properties, as it alkalizes the blood and revives the nervous system. The main ingredient is called miso - a combination of rice, salt, water, and fermented soybeans, shaped into a paste that is similar to peanut butter in texture.
