Organises fires and cooks in oil (5)
I believe the answer is:
fries
'cooks in oil' is the definition.
(I've seen this in another clue)
'organises fires' is the wordplay.
'organises' indicates anagramming the letters (I've seen 'organize' mean this).
'fires' with letters rearranged gives 'FRIES'.
'and' is the link.
(Other definitions for fries that I've seen before include "Cooks in fat" , "Cooks; chips (Amer.)" , "food for grazing?" .)
