Misoshiru

Miso soup is a traditional Japanese soup consisting of a dashi stock into which softened miso paste is mixed. In addition, there are many optional ingredients (various vegetables, tofu, abura-age, etc.) that may be added depending on regional and seasonal recipes, and personal preference. In Japanese food culture, miso soup is a representative of soup dishes served with rice. Miso soup is also called omiotsuke (御味御付). Along with suimono (clear soup seasoned with a small amount of soy sauce and salt in a dashi stock), miso soup is considered to be one of the two basic soup types of Japanese cuisine. The type of miso paste chosen for the soup defines a great deal of its character and flavor. Miso pastes (a traditional Japanese seasoning produced by fermenting soybeans with salt and the fungus Aspergillus oryzae, known in Japanese as kōjikin [ja] (麹菌), and sometimes rice, barley, or other ingredients) can be categorized into red (akamiso), white (shiromiso), or mixed (awase). There are many variations within these themes, including regional variations, such as Shinshū miso or Sendai miso [ja].
