Put a tablespoon of drippings in a kettle, and when it is hot cut up an onion fine and fry in the hot fat, cover closely. Put in potatoes, which have been previously pared, washed, quartered and well salted. Cover them tight and stew slowly until soft, stirring them occasionally. Then heat in a spider a little drippings. Brown in this a spoon of flour and add some soup-stock, vinegar and chopped parsley. Pour this over the potatoes, boil up once and serve.
