Unusually precise cooking instructions (7)
I believe the answer is:
recipes
'cooking instructions' is the definition.
(I've seen this before)
'unusually precise' is the wordplay.
'unusually' indicates anagramming the letters.
'precise' is an anagram of 'RECIPES'.
(Other definitions for recipes that I've seen before include "Instructions for dishes" , "Instructions for making" , "instructions for cook" , "formulae" , "Cooking instructions" .)
