Olive oil flavored with porcini mushroom. Olive oil is a wonderful natural preservative that has been used since the ancient Greeks. Many perishable products were stored in oil, for example, soft and hard cheeses, as well as herbs and plant parts. And they noticed that during long-term storage, they give their aroma and useful properties to the oil. In the modern world, this approach is called the cold extraction method, it is used less and less, because it requires a lot of financial and time costs. Today, most manufacturers add ready-made extracts of herbs and plants to the oil. Porcini mushroom oil is made by cold extraction, i.e. by prolonged infusion of porcini mushrooms in olive oil. Traditional recipe and real taste are important for us.
