Cut one slice bacon in small pieces and cook five minutes with two tablespoons butter. Remove bacon, add one finely chopped shallot, and fry two minutes; then add six chickens’ livers cleaned and separated, and cook two minutes. Add two tablespoons flour, one cup Brown Stock, one teaspoon lemon juice, and one-fourth cup sliced mushrooms. Cook two minutes, turn into a serving dish, and sprinkle with finely chopped parsley.
