Soy sauce is a dark, salty liquid made from fermented soybeans, wheat, salt, and water. It is a staple condiment in many Asian cuisines, particularly in Chinese, Japanese, and Korean dishes. The fermentation process gives soy sauce its rich flavor and aroma, making it a popular ingredient for seasoning and marinating foods. There are different types of soy sauce, including light soy sauce and dark soy sauce, each with unique flavors and uses. Light soy sauce is typically saltier and used for seasoning, while dark soy sauce is thicker and sweeter, often used for adding color to dishes.
