4 TB butter or oil
3/4 cup broth
2 TB flour
1 cup mushrooms, celery, onion or whatever
1 cup sour cream
Saute mushrooms in 2 TB oil or butter. In separate pan, melt 2 TB butter or oil and whisk in flour. Cook for one minute over medium heat and whisk in sour cream and broth. Add mushrooms. Notes: this makes the condensed version that you would use in recipes. If you want to serve it as a soup, dilute it with water or milk.
