Miso soup (味噌汁 misoshiru ) 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.
Wappani (wappani (わっぱ煮 )) is a miso soup based dish unique to Awashima island off the coast of Niigata, Japan. A cedar
flask ("wappa") is filled with miso soup, fish and vegetables and it is
heated by dropping in hot rocks, which quickly bring it to a simmer.
Hot rocks retain their heat for hours after being taken from the fire,
so a hot meal can be prepared without the use of fire.
Dashi (出汁, だし) is a class of soup and cooking stock used in Japanese cuisines. Dashi forms the base for miso soup, clear broth, noodle broth, and many kinds of simmering liquid.
