Red rice vinegar is a type of vinegar made from fermented red rice. It is commonly used in Asian cuisine, particularly in Chinese and Vietnamese dishes. The fermentation process gives it a distinct flavor that is slightly sweet and tangy, making it a popular choice for dressings, marinades, and dipping sauces. This vinegar is often praised for its health benefits, as it contains antioxidants and may aid digestion. It is typically darker in color compared to other vinegars, such as white rice vinegar, and can add a unique depth of flavor to various recipes.
