醬油 (jiàngyóu) is a traditional Chinese condiment made from fermented soybeans, wheat, salt, and water. It is commonly used in Asian cuisine to enhance the flavor of dishes, providing a savory, umami taste. There are various types of 醬油, including light and dark varieties, each with distinct flavors and uses in cooking. 醬油 is not only popular in China but also widely used in other countries, such as Japan and Korea, where it is known as shoyu and ganjang, respectively. It can be used for marinating, dipping, or as a seasoning in soups and stir-fries, making it a versatile ingredient in many recipes.
