Ready to accept English chef’s first guide to food preparation (6)
I believe the answer is:
recipe
'guide to food preparation' is the definition.
(guide for preparing food)
'ready to accept english chef's first' is the wordplay.
'ready' becomes 'ripe' (similar in meaning).
'to accept' is an insertion indicator.
'english' becomes 'e' (abbreviation).
'chef's first' becomes 'c' (rst letter of 'chef').
'e'+'c'='ec'
'ripe' going around 'ec' is 'RECIPE'.
(Other definitions for recipe that I've seen before include "Kitchen directions" , "Kitchener's instructions" , "Directions for making something" , "Directions for cooking the turkey e.g." , "Formula for food dish" .)
