The truffle is a tuber which develops some 10 cm deep in the soil in symbiosis with the roots of oaks,
hazel trees and some pines.
The pig with its powerful smell contributes a great deal to help unearth truffles from underneath trees.
Both Provence and Périgord are the main producing areas in France.
