In a large frying pan, melt the butter. Saute mushrooms in butter until tender (about 5 minutes). Mix flour and chicken base together. Sprinkle over mushrooms. Cook one more minute, stirring. Add sour cream, lemon juice and all seasonings. Cook 2 to 3 minutes more, stirring. We use chicken broth or chicken bouillon. If you use a vegetable broth this is a vegetarian dish. If you can resist digging in right away, cook this ahead of time to give the flavors a chance to mellow. At serving time, rewarm carefully over low heat. This is wonderful as a main dish served over rice, noodles or fettucini Alfredo.
