An exquisite mixture of white truffles and porcini mushrooms with cold pressed extra virgin olive oil is what makes this much appreciated sauce. Feel free to use this sauce on toasted Italian bread, pasta and even dark or white meats! Italy has an ancient heart. At the heart, in Umbria, a region of woods and hills, the land offers one of its most mysterious and precious fruits: the truffle. Truffles are an underground fungus, first discovered in Roman times, which can only be found thanks to its aroma.
