In very hot weather there is nothing so refreshing either for lunch or dinner as a cup of Iced Soup.
1 1/2 pints of very good stock, 1 lb. of tomatoes, 1 small stick of celery (or when this is out of season, 1 teaspoonful of celery seed), salt and pepper.
Quarter the tomatoes and cook them in the stock for 1 hour or more, flavouring with the celery and salt and pepper. Drain through a colander into a basin and put in an ice-box or in a cool larder till quite cold. Half an hour before required surround the basin with ice and a little freezing salt—or failing this, put a small lump of ice in the basin. Serve in cups.
