Miso

is a traditional Japanese seasoning produced by fermenting rice, barley, and/or soybeans with salt and the fungus kōjikin, the most typical miso being made with soy. The result is a thick paste used for sauces and spreads, pickling vegetables or meats, and mixing with dashi soup stock to serve as miso soup called misoshiru, a Japanese culinary staple. High in protein and rich in vitamins and minerals, miso played an important nutritional role in feudal Japan.
