While they are cooking prepare a sauce by browning 2 tablespoons of flour and 2 tablespoons of butter. When light brown, ass 1/2 teaspoon of chives and 1 tablespoon of parsley. After it is nicely browned, add enough beef stock to make a sauce. Cook for 10 minutes, then add the mushrooms mixture and lemon juice and stir. Add 4 tablespoons of sour cream and serve.
