Roast Beef Soup

To a good loin roast add six tablespoons of vinegar and small piece of butter; salt and pepper; stick six cloves in the roast; sprinkle two tablespoons of cinnamon and sift one cup of flour over it. Put in oven in deep pan or kettle with a quart of boiling water; roast until it is about half done and then strain over it three-fourths of a can of tomatoes; finish roasting it and when done add celery-salt to suit the taste, and one cup of sweet cream and some catsup, if preferred.
