Right piece chopped up according to recommended culinary procedure (6)
I believe the answer is:
recipe
'recommended culinary procedure' is the definition.
'recipe' can be an answer for 'procedure' (thesaurus). I'm not sure about the 'recommended culinary' bit.
'right piece chopped up' is the wordplay.
'right' becomes 'r' (abbreviation).
'chopped up' indicates anagramming the letters.
'piece' is an anagram of 'ecipe'.
'r'+'ecipe'='RECIPE'
'according to' acts as a link.
Can you help me to learn more?
(Other definitions for recipe that I've seen before include "A baking formula" , "Method for cooking" , "List of ingredients" , "Step by step method" , "Cook's formula" .)
