My Man's Favorite Soup (Stroganoff Soup)
To adjust the thickness of the soup, use more or less flour. You may also use cream instead of milk for a thicker base. To make a heartier soup (although this is plenty hearty already), you can use more beef or mushrooms. You really must add the cheese and sour cream at the end, it completes the whole meal. This recipe is really hard to mess up; the measurements do not need to be perfect.
