Mince four ounces of leeks, six ounces of carrots, four ounces of turnip-cabbage, two ounces of celery, four ounces of turnips, and four ounces of onions. Place four ounces of butter into a saucepan on the fire, and when hot, add to it the finely minced vegetables and moisten with two quarts of white broth: boil, skim and cook slowly. As soon as the vegetables are well done, drain them, and pound them in a mortar, diluting the puree with some of its broth; strain through a sieve or tammy, heat it to a boiling point without letting it boil, then thicken with egg-yolks, cream and fine butter (No. 175.)
