The recipes are exact (7)
I believe the answer is:
precise
'exact' is the definition.
(I know that exact can be written as precise)
'the recipes' is the wordplay.
'recipes' can be anagrammed to 'PRECISE'.
But, I'm not sure how this is indicated.
'are' is the link.
Can you help me to learn more?
(Other definitions for precise that I've seen before include "Express" , "with accuracy" , "Highly accurate and sharply exact" , "Exact like recipes" , "'Exact, accurate (7)'" .)
