Miso: Miso is fermented soybean paste made by inoculating a mixture of soybeans, salt and grains (usually barley or rice) with koji, a beneficial mold. Aged for up to 3 years, miso is undeniably salty, but a little goes a long way. Akamiso (red miso), made from barley or rice and soybeans, is salty and tangy, and the most commonly used miso in Japan. Use in marinades for meat and oily fish, and in long-simmered dishes. Shiromiso (sweet or white miso), made with soy and rice, is yellow and milder in flavor; use for soup, salad dressings and sauces for fish or chicken.
