The white truffle grows happily in the mountainous woods of Piedmont, where seeking them out is very big business indeed. Once there must have been a time when it was a simple natural food resource like berries and wild mushrooms. In the area around Alba, it is especially popular and many families spend happy hours with their dogs seeking out the tubers for household use. They are always used simply. If you cannot find a fresh truffle, make the black truffle recipe instead.
