Most commonly used korean sauces are soy sauce, sesame oil, bean paste and red pepper paste.
Bean paste is a concentrated, savory paste made from soybeans–often mixed with a grain such as rice, barley, or wheat–that is fermented with a yeast mold and then combined with salt and water. The mixture is aged from one month to three years. While it is a good source of protein and carbohydrates, miso is, nonetheless, high in sodium and should be consumed sparingly if you are salt-sensitive.
