Potato Soup ‘Alla Romana’
Parboil four large potatoes in one quart of water, when half-cooked strain off the water and pour one pint of boiling water on the potatoes; add one bay leaf, half an onion, one head of celery, and some chopped parsley. Boil over a slow fire in an earthen pan, add two ounces of butter and two tablespoonfuls of flour, and mix well. Rub the potatoes through a sieve into an earthen pot, add boiling milk, a little at a time, and serve hot.
