Sauces are not normally eaten by themselves; they add [[flavour]], [[moisture]], and visual appeal to another dish. Sauces are an essential element in cuisines all over the world. The main sauces of [[French cuisine]] are built on a basis of [[roux]], which is just flour and the liquid part of butter. Examples from Italian cuisine are the egg, cheese and [[ham]] sauce called ''[[Carbonara]]''; the ground [[meat]] sauce called [[Bolognese sauce|''bolognese'']], and the [[herb]]s and [[garlic]] sauce called ''[[pesto]]''. Bottled sauces can be poured over food when it is served. An example would be the [[tomato]]-based sauce that is usually poured over [[spaghetti]]. Gravy is a brown sauce served with meat. ''Sauce'' is a [[French language|French]] word taken from the [[Latin]] ''salsus'', meaning ''salted''. Possibly the oldest sauce recorded is ''[[garum]]'', the [[fish sauce]] used by the [[Ancient Rome|Romans]]. Sauces need a liquid component, but some sauces (for example, [[pico de gallo|pico de gallo salsa]] or [[chutney]]) may contain more solid elements than liquid. Sauces may be used for savoury 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]]. Some sauces are commercial products like [[Worcestershire sauce]], [[HP sauce]], [[soy sauce]] or [[ketchup]]. In French cuisine they are freshly prepared by the chef. Sauces for salads are called [[salad dressing]]. A cook who specializes in making sauces is a [[saucier]]. ==French cuisine== [[File:Bearnaise.JPG|thumb|250px|[[Béarnaise sauce]] (''Sauce béarnai
