Soy sauce is a savory condiment made from fermented soybeans, wheat, salt, and water, with a rich umami flavor that adds depth to many dishes. It has a dark, thin, and slightly oily consistency, providing a salty and slightly sweet taste that enhances the overall flavor profile. Widely used in Asian cuisines such as Chinese, Japanese, and Korean, soy sauce serves as a marinade, dipping sauce, or seasoning for stir-fries, sushi, and soups. Historically, it dates back over 2,500 years in China, where it was originally developed as a way to preserve soybeans and as a fundamental flavor component in traditional cooking.
