I've heard about it, but… 5 – What is miso?

Miso soup is a traditional Japanese soup consisting of a stock called “dashi” into which softened miso paste is mixed. Many ingredients are added depending on regional and seasonal recipes, and personal preference. The choice of miso paste for the miso soup defines a great deal of its character and flavor. Miso pastes 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. According to Japanese custom, the solid ingredients are chosen to reflect the seasons and to provide contrasts of color, texture, and flavor. Thus negi and tofu, a strongly flavored ingredient mixed with a delicately flavored ingredient, are often combined. Ingredients that float, such as wakame seaweed, and ingredients that sink, such as potatoes, are also combined. Ingredients may include mushrooms, potatoes, seaweed, onion, shrimp, fish, and grated or sliced daikon. Nearly any Japanese ingredient is added to some type of misoshiru. However, misoshiru does not typically contain many ingredients beyond the stock and miso.
