Umble evolved from numble (after the French nomble), meaning' deer's innards' . </P> <P> It has occasionally been suggested that' umbles' were considered inferior food and that in medieval times, the pie was often served to lower - class people, possibly following speculation in Brewer's Dictionary of Phrase and Fable but there is little evidence for this . Early references in cookbooks such as Liber Cure Cocorum present a grand dish with exotic spices . </P>
