Fires made up for cooks (5)
I believe the answer is:
fries
'for cooks' is the definition.
(frying is a kind of cooking)
'fires made up' is the wordplay.
'made up' indicates an anagram.
'fires' is an anagram of 'FRIES'.
(Other definitions for fries that I've seen before include "Cooks in fat" , "Cooks; chips (Amer.)" , "food for grazing?" .)
