Sauces are an important component of dishes that can enhance taste, moisture, and appearance. They are usually thick liquids that add flavor, richness, and appeal to foods. Common sauces include white sauce, veloute, hollandaise, brown sauce, and tomato sauce. Sauces require careful preparation, such as using a roux to thicken and avoiding problems like separation. Proper storage and reconstitution of stocks, sauces and soups is also important for food safety and quality.
