Quality dried trompettes should resemble flowers and can be as long as three inches. Despite its stem, the black trompettes are fully edible and both stem and cap have the same delicious flavor and texture. When reconstituted, the excellent buttery flavor of this mushroom comes to fore. These mushrooms complement fish entrees very well. They are also a nice addition to soups and casseroles. After reconstituting they can be an interesting ingredient in vegetarian dishes. Saut a few of them and then add to your favorite wild rice dish. As with other dried mushrooms these should be reconstituted in wine, stock or water. After they are softened you can use them in your dish.
