Maiden to consume flesh (4)
I believe the answer is:
meat
'flesh' is the definition.
(flesh is meat)
'maiden to consume' is the wordplay.
'maiden' becomes 'm' (cricket abbreviation).
'to consume' becomes 'eat' (eating is a kind of consuming).
'm'+'eat'='MEAT'
(Other definitions for meat that I've seen before include "Beef, chicken, pork etc" , "The flesh of animals as food" , "Ham, pork, chicken etc" , "Food for carnivores" , "17 [ESSENCE]" .)
