This recipe is taken from the Menagier de Paris, which was written around 1390 by a wealthy Parisian. It appears in a section headed Potages lians de chair, that is to say, cream soups that had been pounded in a pestle, passed through a strainer, or "tammy," and thickened with eggs and bread - to some extent the forerunners of the eighteenth century's thickened soups.
