Clean carrots and turnips and cut into strips or fancy shapes; there should be one and one-fourth cups carrots and one-half cup turnips. Cook separately in boiling salted water until soft. Drain, and add one and one-fourth cups cooked peas. Reheat in a sauce made of three tablespoons butter, three tablespoons flour, one cup chicken stock, and one-half cup cream. Season to taste with pepper and salt, and just before serving add yolks two eggs and one-half tablespoon lemon juice.
