Meat is animal flesh that is used as food. Most often, this means the skeletal muscle and associated fat, but it may also describe other edible tissues such as organs, livers, skin, brains, bone marrow, kidneys, or lungs. The word meat is also used by the meat packing industry in a more restrictive senseâ€”the flesh of mammalian species (pigs, cattle, etc.) raised and prepared for human consumption, to the exclusion of fish and poultry. In cooking, a sauce is liquid or sometimes 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. Sauce is a French word taken from the Latin salsus, meaning salted. Sauces need a liquid component, but some sauces (for example, salsa or chutney) may contain more solid elements than liquid. Sauces are an essential element in cuisines all over the world. Sauces may be ready made sauces, usually bought, such as soy sauce, or freshly prepared by the cook; such as BÃ©chamel sauce, which is generally made just before serving. Sauces for salads are called salad dressing. Sauces made by deglazing a pan are called pan sauces. A cook who specializes in making sauces is a "saucier".
