The main components of classic stroganoff are pieces of beef in a sour cream and mustard sauce. Often times mushrooms and dill are also found in the recipe. Beef Stroganoff is a Russian dish but it has gained popularity around the world. Some classic seasonings within stroganoff sauce are sugar, black pepper, and worcestershire sauce. I love using the worcestershire when making stroganoff with venison, because it offsets some of the gamey taste.
