Sauce
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. "Sauce" is a French word taken from the Latin "salsa", meaning "salted". Possibly the oldest recorded European sauce is garum, the fish sauce used by the Ancient Romans, while doubanjiang, the Chinese soy bean paste is mentioned in "Rites of Zhou" in the 3rd century BC. Sauces need a liquid component. 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. They may be freshly prepared by the cook, especially in restaurants, but today many sauces are sold premade and packaged like Worcestershire sauce, HP Sauce, soy sauce or ketchup. Sauces for salad are called salad dressing. Sauces made by deglazing a pan are called pan sauces. A chef who specializes in making sauces is called a saucier. Cuisines. British. In  traditional British cuisine, gravy is a sauce used on roast dinner. The sole survivor of the medieval bread-thickened sauces, bread sauce is one of the oldest sauces in British cooking. Apple sauce, mint sauce and horseradish sauce are used on meat (usually on pork, lamb and beef respectively). Redcurrant jelly, mint jelly, and white sauce may also be used. Salad cream is sometimes used on salads. Ketchup and brown sauce are used on fast-food type dishes. Strong English mustard is also used on various foods, as is Worcestershire sauce. Custard is a popular dessert sauce. Other popular sauces  include mushroom sauce, marie rose sauce (as used in a prawn cocktail), whisky sauce (for serving with haggis), Albert sauce (horseradish sauce to enhance flavour of braised beef) and cheddar sauce (as used in cauliflower or macaroni and cheese). In contemporary British cuisine, owing to the wide diversity of British society today, there are also many sauces that are of British origin but based upon the cuisine of other countries, particularly former colonies such as India. Chinese. There are many varied cuisines in China, but many of them compose dishes from sauces including different kinds of soy sauce, fermented bean  paste including doubanjiang, chili sauces, oyster sauce, and also many oils and vinegar preparations. These ingredients are used to build up a range of different sauces and condiments used before, during, or after cooking the main ingredients for a dish: In some Chinese cuisines, such as Cantonese, dishes are often thickened with a slurry of cornstarch or potato starch and water. See "List of Chinese sauces" Filipino. Filipino cuisine typically uses "toyomansi" (soy sauce with kalamansi lime) as well as different varieties of suka, patis, bagoong and banana ketchup, among others. French. Sauces in French cuisine date back to the  Middle Ages. There were many hundreds of sauces in the culinary repertoire. In "cuisine classique" (roughly from the end of the 19th century until the advent of "nouvelle cuisine" in the 1980s), sauces were a major defining characteristic of French cuisine. In the early 19th century, the chef Marie-Antoine Carême created an extensive list of sauces, many of which were original recipes. It is unknown how many sauces Carême is responsible for, but it is estimated to be in the hundreds. Most of them have been listed in Carême reference cookbook "The art of French Cuisine in the 19th  century" (The French Title: "L'art de la cuisine française au XIXe siècle"). Carême considered the four "grandes sauces" to be Espagnole, Velouté, Allemande, and Béchamel, from which a large variety of petites sauces could be composed. In the early 20th century, the chef Auguste Escoffier refined Carême's list of basic sauces in his classic "Le Guide culinaire", which in the most recent 4th edition that was published in 1921, listed the foundation or basic sauces as Espagnole, Velouté, Béchamel, and Tomate. Sauce Allemande, which was mentioned as a preparation of Velouté made with egg yolks, is replaced by Sauce  Tomate. One other sauce-de-base that is mentioned in "Le Guide culinaire" is Sauce Mayonnaise, which Escoffier wrote was a sauce Mère akin to the sauces Espagnole and Velouté due to the number of derivative sauces that can be made. In "A Guide to Modern Cookery", an English abridged translation of Escoffier's 1903 edition of "Le Guide culinaire", Hollandaise was included in the list of basic sauces, which made for a list that is identical to the list of five fundamental "French Mother Sauces" that is acknowledged by a variety of sources: A sauce which is derived from  one of the mother sauces by augmenting with additional ingredients is sometimes called a "daughter sauce" or "secondary sauce". Most sauces commonly used in classical cuisine are daughter sauces. For example, béchamel can be made into Mornay by the addition of grated cheese, and espagnole becomes bordelaise with the addition of reduction of red wine, shallots, and poached beef marrow. A specialized implement, the French sauce spoon, was introduced in the mid-20th century to aid in eating sauce in French cuisine, is enjoying increasing popularity at high-end restaurants. Indian. Indian cuisines use sauces such as tomato-based sauces with  varying spice combinations such as tamarind sauce, coconut milk-/paste-based sauces, and chutneys. There are substantial regional variations in Indian cuisine, but many sauces use a seasoned mix of onion, ginger and garlic paste as the base of various gravies and sauces. Various cooking oils, ghee and/or cream are also regular ingredients in Indian sauces. Indonesian. Indonesian cuisine uses typical sauces such as "kecap manis" (sweet soy sauce), "bumbu kacang" (peanut sauce) and tauco, while popular hot and spicy sauces are sambal, dabu-dabu and rica-rica. Sambal is an umbrella term; there are many, many kinds of sambal. Italian . Italian sauces reflect the rich variety of the Italian cuisine and can be divided in several categories including: Savory sauces used for dressing meats, fish and vegetables. Examples are: Savory sauces used to dress pasta dishes. There are thousands of such sauces, and many towns have traditional sauces. Among the internationally well-known are: Japanese. Sauces used in traditional Japanese cuisine are usually based on "shōyu" (soy sauce), "miso" or "dashi". "Ponzu", citrus-flavored soy sauce, and "yakitori no tare", sweetened rich soy sauce, are examples of shōyu-based sauces. Miso-based sauces include "gomamiso", miso with ground sesame, and  amamiso, sweetened miso. In modern Japanese cuisine, the word "sauce" often refers to Worcestershire sauce, introduced in the 19th century and modified to suit Japanese tastes. Tonkatsu, okonomiyaki, and yakisoba sauces are based on this sauce. Japanese sauce or wasabi sauce is used on sushi and sashimi or mixed with soy sauce to make wasabi-joyu. Korean. Korean cuisine uses sauces such as doenjang, gochujang, samjang, aekjeot, and soy sauce. Latin and Spanish American. Salsas ("sauces" in Spanish) such as pico de gallo (tomato, onion and chili chopped with lemon juice), salsa cocida, salsa verde, chile, and salsa roja are  an important part of many Latin and Spanish-American cuisines in the Americas. Typical ingredients include chili, tomato, onion, and spices; thicker sauces often contain avocado. Mexican cuisine includes sauces which may contain chocolate, seeds, and chiles collectively known by the Nahua name mole (compare guacamole). In Argentinian and Uruguayan cuisine, chimichurri is an uncooked sauce used in cooking and as a table condiment for grilled meat. Peruvian cuisine uses sauces based mostly in different varieties of "ají" combined with several ingredients, most notably salsa huancaína based on fresh cheese and salsa de ocopa based on peanuts or nuts.
