Inaccurate setter's inaccurate recipes (9)
I believe the answer is:
imprecise
'inaccurate' is the definition.
(associated in meaning)
'setter's inaccurate recipes' is the wordplay.
'setter's' becomes 'im' (referring to the person who set the crossword).
'inaccurate' indicates anagramming the letters.
'recipes' is an anagram of 'precise'.
'im'+'precise'='IMPRECISE'
(Other definitions for imprecise that I've seen before include "Not true" , "Inexact" , "not quite right" , "Inaccurate" , "Approximate" .)
