White saikyo miso ozoni is a japanese soup that originates from the kyoto region of japan. It is unique in that the base of the ozoni mochi (rice cake) soup is made from a sweet pale white miso (fermented soybean paste). Aside from the mochi (rice cake) and white miso, other ingredients might include a variety of vegetables, commonly with carrots and daikon radish, but largely dependent upon the region of japan, individual family tradition, and preference. Other ozoni soup add-ins might include taro root (sato imo), mizuna vegetable, mustard greens, spinach, various fish cakes, sweet potatoes, chicken, seafood. The key to kyoto style ozoni is white saikyo miso which originates from kyoto. The miso is a very pale white color in comparison to traditional miso which tends to range from yellow to dark brown and red. Saikyo white miso tends to have a lower sodium content because of the way that it is made, and as such, has a much sweeter flavor.
