Pesto (Italian pron. /'pesto/, genoese pron. /'pestu/, contracted past participle of pestâ: "to pound, to crush," in reference to the crushed herbs and garlic in it, from Latin root of pestle) is a sauce that originates in the city of Genoa in the Liguria region of northern Italy (pesto alla genovese).
At least one other well-known variant exists, the pesto alla siciliana, a sauce from Sicily similar to the basic Genoese pesto recipe with the addition of tomato and much less basil.

[edit] Origin and ingredients
The ancient Romans ate a cheese spread called moretum, which may sometimes have been made with pesto. The herb likely first came from North Africa.
Pesto alla genovese in its classic basic form has Genoese basil, salt, garlic, Ligurian extra virgin olive oil "Taggiasco", European pine nuts, and a grated hard cheese, usually Parmigiano Reggiano but sometimes Grana Padano, Pecorino Sardo, or Pecorino Romano[citation needed].
As the saying goes, the best possible pesto is made of basil grown in the greenhouses of the Genoa district of Prà. This original recipe is said to have originated with the Passalaqua family, which has resided in the region for generations.[citation needed]
Originally pesto was (and sometimes is still) prepared in a marble mortar with wooden pestle. First the basil leaves are washed and dried and then put in the mortar together with garlic and some coarse crystals of sea salt, crushed to a creamy consistency. Then the pine nuts are added and crushed together. When the pine nuts are well incorporated in the "cream", the two grated cheeses (Parmigiano e Pecorino) plus olive oil can be added and stirred together with a wooden spoon. The sauce is now ready. In a tight jar, or simply in an air-tight plastic container, pesto can last in the fridge up to a week. Pesto can also be frozen, if needed.
Commercial lower quality pesto, usually sold in small jars, is commonly available in stores in green (original) or red (with sun-dried tomatoes or red bell peppers) varieties, produced by major manufacturers or under a 'generic' or 'cheaper' brand. In this quality pesto, cashew nuts or walnuts are often used instead of pine nuts, as they are less expensive and have a similar texture. Cheaper oils may also be used.
Pesto is commonly used on pasta, traditionally with Mandilli de Sea (Genovese dialect - literally "silk handkerchieves" - for lasagna)[1], strozzapreti or trenette. It is sometime used in minestrone as well. It is very important never to cook pesto because basil when heated gets bitter. Pesto is also often served on sliced beef, tomatoes and sliced boiled potatoes.
[edit] Variations
A slightly different version of the sauce exists in Provence, where it is known as Pistou. In contrast with the genovese pesto, pistou is generally made with olive oil, basil and garlic only: while cheese may be added, usually no nuts are included. Pistou is used in the typical soupe au pistou, a hearty vegetable soup with pistou flavour. The sauce did not originally contain basil, however. Instead, cheese and olive oil were the main constituents.
Other existing ingredient variations include: arugula (instead of or in addition to basil), black olives, lemon rind, coriander or mushrooms.[2] A German variety uses ramsons leaves instead of basil. In the 19th century, Genovese immigrants to Argentina brought pesto recipes with them. A Peruvian variety, known as "Tallarin Verde" (literally "Green Noodles", from Italian tagliarini) is slightly creamier, uses spinach leaves and is served with potatoes and sirloin steak.
[edit] Digestive properties
Basil has been used as a treatment for coughs, skin diseases, and intestinal problems. The seed still finds use as a bulk-forming laxative and diuretic. [3] However, the composition of basil is affected not only by the chemotypes present in its many different varieties, but even by influences such as the time of day of harvest, which may explain contradictory and inconsistent reports that a too-generous helping of pesto may cause a temporary but distressing intestinal reaction in some people.
