Although we would've preferred to be the one to stumble across this in the forest, instead we stumbled across it on swissmiss. Holy smokes, that mushroom is living large.
Matsutake mushrooms (Pine Mushroom) are known for having aphrodisiac properties, and for commanding prices and status in Japan similar to truffles here in the US and Europe. To prepare a Matsutake, slice off the stem (discard), wipe any dirt off the caps with a damp paper towel (never wash), and slice. These mushrooms are best sautéed or in a Japanese broth with sea vegetables.
We do not recommend eating them with cigarettes.
