Famine's counterpart (5)
I believe the answer is:
feast
'famine's counterpart' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for feast that I've seen before include "Abundant meal" , "Celebratory meal" , "Saint's day, for example" , "(Eat) a rich meal" , "Beano" .)
