Crepe is fashioned to be clear-cut (7)
I believe the answer is:
precise
'be clear-cut' is the definition.
(thesaurus)
'crepe is fashioned' is the wordplay.
'fashioned' indicates an anagram.
'crepe'+'is'='crepeis'
'crepeis' anagrammed gives 'PRECISE'.
'to' is the link.
(Other definitions for precise that I've seen before include "Express" , "'Exact, accurate (7)'" , "Specific" , "Exact like recipes" , "with accuracy" .)
