Utilises Sue's recipe (4)
I believe the answer is:
uses
'utilises' is the definition.
('use' can be a synonym of 'utilise')
'sue's recipe' is the wordplay.
'recipe' indicates an anagram.
'sues' is an anagram of 'USES'.
(Other definitions for uses that I've seen before include "Purposes; consumes" , "Takes (drugs)" , "Exercises" , "'Purposes, functions (4)'" , "Puts to a particular purpose" .)
