In cooking, a sauce is a liquid, cream, or semi-solid food, served on or used in preparing other foods.
Most sauces are not normally consumed by themselves; they add flavor, moisture, and visual appeal to a dish.
Sauces are an essential element in cuisines all over the world.
Sauces may be used for sweet or savory dishes.
They may be prepared and served cold, like mayonnaise, prepared cold but served lukewarm like pesto, cooked and served warm like bechamel or cooked and served cold like apple sauce.
