Wild Mushroom Soup with Barley

The combination of barley and mushrooms is an Eastern European favorite, and this soup makes the best of both ingredients by layering the flavor with three kinds of mushrooms. Be sure to use pearl barley for the best results. For a soy-free version, omit the soy sauce and use a soy-free sauce (purchased or homemade) or add some soy-free vegetable broth base or additional salt.
