Cut leg of chicken and breast bones in pieces. Heat oil with paprika in frying pan; add chicken and cook slowly, covered for 30 mminutes, turning once or twice. Add mushroom stems and cook 10 minutes more. Then add flour, smoothing it in to prevent lumps. Add sour cream and cook slowly -do not let it boil -until juices are well-mixed. Add brown gravy, boil, and season with salt, pepper, and lemon juice. Strain and serve with the breasts. Serve on silver platter topped with a sugar glazed pineapple ring and garnished with wild rice.
