Light but filling. Excellent served with a bean salad and good crusty bread. The broth should have a shiny appearance from the cornstarch. Larchwood Inn, Wakefield, Rhode Island
Heat beef broth in large kettle. Saute onions, celery, and carrots in butter and oil until just tender. Transfer with slotted spoon to broth and simmer. Use same oil and butter to saute mushrooms. When done pour mushrooms and liquid into soup. Add wine and bring to a boil. Combine cornstarch and cold water, then add to soup. Heat until slightly thickened and serve.
