Pistou
From Wikipedia, the free encyclopedia
Pistou sauce, or just pistou, is a cold sauce made from cloves of garlic, fresh basil, and olive oil. Some versions also include grated parmesan. Traditionally, the ingredients are crushed and mixed together in a mortar with a pestle, (pistou means pounded in the Provençal language).[1] It is often confused with pesto with which it shares some of the same ingredients, the key difference being the addition of garlic and the absence of pignoli (pine nuts).[2] It is a typical condiment from the Provence region of France that is can be served with pasta dishes or as a spread for bread. But it is most often associated with the Provencal dish Soupe au Pistou, a minestrone like summer soup that includes white beans, green beans, tomatoes, summer squash, potatoes, and vermicelli. These ingredients can be left out or replaced as long as the soup's golden rule about summer vegetables is followed. Thus Pistou soup is not made with, for example, leeks. Some recipes incorporate the pistou into the soup just before serving. [3] Others recommend offering the sauce at the table to be added after the soup is served.[4]
Both pistou and pesto probably share the same origins. The Roman poet Virgil describes a sauce of crushed herbs, garlic, salt, and olive oil.[1] A version with pignoli emerged around Genoa to become pesto, while pistou evolved in the areas around Nice.
Some regions, especially those closer to the Alps, substitute Swiss cheese in the place of parmesan. Whatever cheese is used, it is preferred that it not be a "stringy" cheese, so that when it melts in a hot liquid (like in the pistou soup, for instance) it does not melt into long strands.
