What is Pistou – The French Pesto

PISTOU…or pesto? Pesto is a very commonly known and commercially produced basil/olive oil/garlic condiment used in Italian cuisine. Pistou, it’s lesser known cousin, is a basil/olive oil/garlic condiment used in French cuisine.

The main difference is the pine nuts – which are used in the Italian version and not in the French.

The traditional French version of pistou is made only with garlic, basil, olive oil and salt. It is now common to see it made with Parmesan or other cheeses and sometimes with a tomato thrown in for extra flavoring.

What Does Pistou Mean

The word itself – pistou – is a Provençal word derived from the latin pestare which means to pound. Pistou is made by “pounding” the ingredients together using a mortar and pestle.

Food processors have taken over from the mortar and pestle, but Patricia Wells notes in her cookbook that only by using the traditional method of the mortar and pestle will you be able to retain the bright green color.

The sauce is best made within one to two days of using. To store it longer, cover it with a thin film of olive oil and keep it in the refrigerator. It can also be frozen immediately in tablespoon and 1/2-cup portions.

Pistou can be used as a sauce for pasta or as a flavoring for steamed vegetables, grilled fish and chicken. Perhaps the best known use is in Soupe au Pistou. This Provençal soup showcases a wide variety of garden vegetables.  It certain regions, bacon, sausage or ham is also added. It’s said that this classic of Provençal cuisine was created in the 18th century by a duchess in order to seduce a marquis. Let yourself be seduced by this recipe for Soupe au pistou.
