I wish I could post the scent as it cooked.....
"Matsutake literally means "pine mushroom." Revered throughout Asia, this traditional delicacy is a favorite of Japanese chefs, whose preparations are well-suited to its strong, spicy-clean fragrance and taste. The unique flavor of fresh matsutake mushrooms, (Tricholoma magnivelare),  is owed to the rare conditions under which it grows - under the base of pine trees between 20 to 60 years old. Their magnificently spicy aroma, reminiscent of pine and cinnamon, enhances wild mushroom dishes and makes great stuffed mushrooms. They are high in protein, low in fat and rich in vitamins B1, B2, and D, and are believed to have many healthful properties."
