Dried Mushrooms have been extremely integral to cooking throughout Europe and the Orient for many centuries. Since they've recently been accepted more and more here in the United States, dried mushrooms users have become selective of what they use. Bags that are full of dirt and stems will not be sold here. This is a blend of Shiitake, Porcini, Oyster, Bolete, Wood Ear and Sliced Shiitake mushrooms and is the most economical choice for imparting mushroom flavor into your stocks or soups. Since the shelf life is so long, spoiling mushrooms will soon become a faint memory of the past.
