" Unlike the miso soup served in restaurants, however, which contains lots of little goodies, like seaweed and diced tofu, the miso soup served at a tea kaiseki usually features one central ingredient that breaks the soup's surface. Depending upon the season, you might encounter a square of bean curd, a ball of wheat gluten, or a wheel of daikon radish simmered in dashi until butterscotch sweet. These central ingredients are usually cooked separately before being placed in the soup bowl and crowned with a seasonal garnish, such as fall chestnut, peppery spring shoot, or fragrant summer herb.
