- In cooking, a sauce is liquid, cream, or semi-solid food served on or used in preparing other foods. Sauces are not normally consumed by themselves; they add flavor, moisture, and visual appeal to another dish.
- Sauces need a liquid component, but some sauces (for example, pico de gallo salsa or chutney) may contain more solid components than liquid. Sauces are an essential element in cuisines all over the world.
- Sauces may be used for savory dishes or for desserts. They can be prepared and served cold, like mayonnaise, prepared cold but served lukewarm like pesto, or can be cooked like bechamel and served warm or again cooked and served cold like apple sauce.
